The Sun’s impact on the Earth [1]
Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected
The Earth radiates energy at wavelengths much longer than the Sun because it is colder. Part of this longwave radiation is absorbed by greenhouse gases which then radiate energy into all directions, including downwards and thereby trapping heat in the atmosphere.
This effect is enhanced by increasing greenhouse gas concentrations in the atmosphere due to emissions by human activities such as burning fossil fuels. The main long-lived greenhouse gases are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)
ENERGY AND TIME [2]
– To be aware of the different forms of energy and the time frame necessary for the development of these energy forms.. The student will become familiar with different forms of energy.
– Are energy sources renewable or nonrenewable? You can decide for yourself. If a source of energy is replaced as we use it, so that we can never use it up, it is called renewable
This is an important idea, because it helps us to decide how we should use each of our many sources of energy.. – Energy is all around us and comes from many sources
All About the Ocean [3]
Biology, Earth Science, Oceanography, Geography, Physical Geography. It contains about 1.35 billion cubic kilometers (324 million cubic miles) of water, which is about 97 percent of all the water on Earth
Earth is the only planet in our solar system that is definitely known to contain liquid water.. Although the ocean is one continuous body of water, oceanographers have divided it into five principal areas: the Pacific, Atlantic, Indian, Arctic, and Southern Oceans
The ocean plays a vital role in climate and weather. The sun’s heat causes water to evaporate, adding moisture to the air

16 The Forces that Change the Face of Earth — Earth’s Changing Surface — Beyond Penguins and Polar Bears [15]. Layers of the Earth based on chemical composition and physical properties
Layers of the Earth based on chemical composition and physical properties. Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth
What two types of surface on Earth are most important for absorbing solar energy and keeping the planet warm? [5]
water and thick forests because it is using a “green house affect”. When an object is changing state form liquid to a gas the object is absorbing energy to allow its molecules to expand
When an object is changing state form liquid to a gas the object is absorbing energy to allow its molecules to expand. it cant increase in temperature because it is using the energy that it is absorbing.
They act much like car shock suspension, which absorb energy while keeping car occupants and the car base steady.. because going down the group the size of the atom increases bcz of shielding efffect etc
What are Two Main Causes of Changes to the Earth Surface? [6]
These changes mostly occur in very minute ways which over time accumulates to create the earth’s physical features we observe around us today.. When you look around and you might see a mountain, river, plateau, valleys, or rock boulders
Slow Versus Fast Changes to the Surface of the Earth. But how and what causes these changes to the earth’s surface?
Fast changes occur through the actions of earthquakes, volcanoes, landslides, etc. The focus of this article is the slow change since its action is carried out on all parts of the Earth’s surface.
The Earth’s Structure [7]
The earth is made up of three different layers: the crust, the mantle and the core.. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite
Oceanic crust is denser and thinner and mainly composed of basalt. Continental crust is less dense, thicker, and mainly composed of granite.
It consists of hot, dense, iron and magnesium-rich solid rock. The crust and the upper part of the mantle make up the lithosphere, which is broken into plates, both large and small
The Layers of Earth [8]
Geologists believe that as the Earth cooled, the heavier and denser material sank into the centre, and the lighter ones rose towards the top. Due to this, the outermost layer is made of the lightest materials, such as rocks and granites, and the innermost layer consists of nickel and iron
The inner core is solid and made up of iron and nickel with temperatures up to 5,500oC. Due to its immense heat energy, the inner core is more like the engine room of the Earth.
The outer core is around 1800 miles under the crust and is approximately 1400 miles thick. The inner core has pressures and temperatures so high that the metals are squeezed together and not able to move like a liquid but are forced to vibrate instead of solid.

Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being a water world, the only one in the Solar System sustaining liquid surface water
The remaining 29.2% of Earth’s surface is land, most of which is located in the form of continental landmasses within one hemisphere, Earth’s land hemisphere. Most of Earth’s land is somewhat humid and covered by vegetation, while large sheets of ice at Earth’s polar deserts retain more water than Earth’s groundwater, lakes, rivers and atmospheric water together
How Has The Earth Changed? [10]
The earth has not always looked the way it looks today. In other words, the United States one billion years ago was in a totally different location than it is today!! How does this happen? And why does this happen? Let’s take a look
What about the internal structure of the Earth? Our best clues about the interior come from waves that pass through the Earth’s material. When earthquakes shake and shatter rock within the Earth, they create seismic waves which travel outward from the location of the quake through the body of the Earth
The velocity and characteristics of the waves depend on the type of rock or molten material they traverse.. Studies of seismic waves have revealed two important types of layering in the Earth: chemical and physical
The Sun’s impact on the Earth [11]
Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected
The Earth radiates energy at wavelengths much longer than the Sun because it is colder. Part of this longwave radiation is absorbed by greenhouse gases which then radiate energy into all directions, including downwards and thereby trapping heat in the atmosphere.
This effect is enhanced by increasing greenhouse gas concentrations in the atmosphere due to emissions by human activities such as burning fossil fuels. The main long-lived greenhouse gases are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)
Information on Earth’s Water [12]
Earth is known as the “Blue Planet” because 71 percent of the Earth’s surface is covered with water. Water also exists below land surface and as water vapor in the air
be the same water that once trickled down the back of a wooly mammoth. The Earth is a closed system, meaning that very little matter, including water, ever leaves or enters the atmosphere; the water that was here billions of years ago is still here
The earth has an abundance of water, but unfortunately, only a small percentage (about 0.3 percent), is even usable by humans. The other 99.7 percent is in the oceans, soils, icecaps, and floating in the atmosphere
The Earth’s Layers Lesson #1 [13]
Many geologists believe that as the Earth cooled the heavier, denser materials sank to the center and the lighter materials rose to the top. Because of this, the crust is made of the lightest materials (rock- basalts and granites) and the core consists of heavy metals (nickel and iron).
The mantle is much hotter and has the ability to flow. The Outer and Inner Cores are hotter still with pressures so great that you would be squeezed into a ball smaller than a marble if you were able to go to the center of the Earth!!!!!!
The crust is only about 3-5 miles (8 kilometers) thick under the oceans(oceanic crust) and about 25 miles (32 kilometers) thick under the continents (continental crust). The temperatures of the crust vary from air temperature on top to about 1600 degrees Fahrenheit (870 degrees Celcius) in the deepest parts of the crust
Planet Earth — Everything you need to know [14]
While scientists continue to hunt for clues of life beyond Earth, our home planet remains the only place in the universe where we’ve ever identified living organisms.. Earth is the fifth-largest planet in the solar system
Earth has a diameter of roughly 8,000 miles (13,000 kilometers) and is mostly round because gravity generally pulls matter into a ball. But the spin of our home planet causes it to be squashed at its poles and swollen at the equator, making the true shape of the Earth an “oblate spheroid.”
Water covers roughly 71% of Earth’s surface, with most of that water located in our planet’s oceans. About a fifth of Earth’s atmosphere consists of oxygen, produced by plants.
K4 Modules: Earth System [15]
You may know that a round object is called a sphere. You may not know that the word sphere has a second meaning
These four spheres are land, water, living things, and air. Everything on Earth exists in one of these spheres.
There are high mountains like the Rockies and Andes (shown in red). There are huge plains or flat areas like those in Texas, Iowa, and Brazil (shown in green)
Earth’s Crust: Elements, Minerals and Rocks [16]
In the previous article in geography section, we have discussed in detail about the interior of the earth. We have seen different layers like crust, core, and mantle
In this article, we focus on how to learn fast the composition of the earth’s crust – i.e, different elements, minerals, and rocks.. – The earth is composed of various kinds of elements.
– The rest is constituted by elements like titanium, hydrogen, phosphorous, manganese, sulphur, carbon, nickel and others.. – The elements in the earth’s crust are rarely found exclusive but are usually combined with other elements to make various substances.
Absorption / reflection of sunlight [17]
Sunlight travels through space at nearly 300,000 kilometers per second (186,000 miles per second). When sunlight strikes the Earth, it is mostly reflected or absorbed
Changes in the proportion of incoming solar radiation that is reflected instead of absorbed depends on the composition of Earth’s surface and atmosphere, and can alter global climate and ecosystems.. – What is the absorption and reflection of sunlight?
– How human activities influence the absorption and reflection of sunlight. The amount of sunlight that is absorbed or reflected by Earth’s surface and atmosphere affects the energy budget, the amount of energy available on Earth that drives system processes and phenomena
2B: Following the Energy Flow [18]
Energy from the sun heats Earth’s surface, warms the atmosphere, provides energy for photosynthesis, causes evaporation, drives the weather and water cycles, and powers the ocean currents. In the astronaut photograph at right, taken from the International Space Station, you can see the sun setting through the atmosphere.
To get a sense of the thickness of the troposphere and stratosphere, two important layers of the atmosphere, try this simple exercise. Use a compass to draw a circle with a radius of 127 mm
The 1 mm line, that your pencil draws, represents the average thickness of the the first two layers of the atmosphere: the troposphere, the region of weather, and the stratosphere, which protects us from most of the Sun’s harmful ultraviolet (UV) radiation. As you work through the these labs keep this relative scale in mind.
How Much Water is There on Earth? [19]
But just how much water exists on, in, and above our planet? Read on to find out.. • Water Science School HOME • Water Basics topics •
All Earth’s water, liquid fresh water, and water in lakes and rivers. But just how much water exists on, in, and above our planet? About 71 percent of the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water
Thanks to the water cycle, our planet’s water supply is constantly moving from one place to another and from one form to another. Things would get pretty stale without the water cycle!
