Earth – NASA Solar System Exploration [2]
Our home planet is the third planet from the Sun, and the only place we know of so far that’s inhabited by living things. While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface
All of the planets, except for Earth, were named after Greek and Roman gods and goddesses. However, the name Earth is a Germanic word, which simply means “the ground.”Potential for Life
Most notably, Earth is unique in that most of our planet is covered in liquid water, since the temperature allows liquid water to exist for extended periods of time. Earth’s vast oceans provided a convenient place for life to begin about 3.8 billion years ago.

Terrestrial planet [6]
A terrestrial planet, telluric planet, or rocky planet, is a planet that is composed primarily of silicate rocks or metals. Within the Solar System, the terrestrial planets accepted by the IAU are the inner planets closest to the Sun: Mercury, Venus, Earth and Mars
Terrestrial planets are generally studied by geologists, astronomers, and geophysicists.. Terrestrial planets have a solid planetary surface, making them substantially different from the larger gaseous planets, which are composed mostly of some combination of hydrogen, helium, and water existing in various physical states.
The large rocky asteroid 4 Vesta has a similar structure; possibly so does the smaller one 21 Lutetia.[4] Another rocky asteroid 2 Pallas is about the same size as Vesta, but is significantly less dense; it appears to have never differentiated a core and a mantle. The Earth’s Moon and Jupiter’s moon Io have similar structures to the terrestrial planets, but Earth’s Moon has a much smaller iron core

The comparative study of planets then is essential to understanding the relationship between planetary development and the origin and evolution of living systems.. As a minimum for life to arise and evolve on a planet, the persistence of liquid water and a hydrologic cycle operating in concert with geochemical cycles of the biogenic elements would appear to be required

Shaping the Planets: Tectonism [9]
Tectonism is the faulting or folding or other deformation of the outer layer of a planet. It happens very slowly, on the scale of millions of years
As they have cooled, they have formed a strong outer layer — the lithosphere. Continued movement of hot material in the interior of the planet causes the surface to deform
Each planet has a unique history and unique tectonic features. Large planets, such as Venus, Earth, and Mars, are large enough to have remained hot inside and still have active tectonism
Seismic Waves Are Most Useful For Mapping — I Hate CBT’s [10]
Question: The crust of the Earth is covered by about ________ water in the hydrosphere.. Question: Which of the following layers of the earth is unique among the terrestrial planets?
Answer: about 5 times denser, like the Mercury and Venus.. Question: The relative size of the atmosphere layer as compared to the solid part of Earth is most similar to
Question: What can we conclude about the structure of Earth’s interior knowing that the average density of Earth is higher than the average density of the rock on the continents and seafloor?. Answer: that Earth’s most dense material must be beneath the surface
What Makes the Earth a Unique Planet? [11]
Earth is, in many respects, like the other planets of the solar system. It orbits in the same plane and in the same direction
But the Earth is also unique; it has extensive surface deposits of liquid water, which is the essential medium for life as we know it.. The formation of the Earth happened 4.5 billion years ago
For instance, Earth is about 150 million kilometers from the Sun. That’s close enough to maintain liquid water but not so close as to boil it away.
Terrestrial Planets: Definition & facts [12]
Terrestrial planets are Earth-like planets made up of rocks or metals with a hard surface. Terrestrial planets also have a molten heavy-metal core, few moons and topological features such as valleys, volcanoes and craters.
During the formation of the solar system, there were likely more terrestrial planetoids, but they either merged with each other or were destroyed.. The definition of “planet” from the International Astronomical Union is controversial
Scientists are divided in particular on the third point, with some saying that it’s hard to define how much clearing a planet does, while others saying a world like Pluto would clear less than a world like Earth. This means that some astronomers argue that the dwarf planet Pluto should be classified as a planet, along with various other dwarf planets scattered throughout the solar system.
Parts of the Atmosphere [13]
We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions.

Other planets and moons have very different atmospheres, and some have no atmospheres at all.. The atmosphere is so spread out that we barely notice it, yet its weight is equal to a layer of water more than 10 meters (34 feet) deep covering the entire planet
Unlocking the Mysteries of Planet Mercury [14]
Mercury’s density implies that a metal-rich core occupies at least 60% of the planet’s mass, a figure twice as great as for Earth! MESSENGER acquired compositional and mineralogical information to distinguish among the current theories for why Mercury is so dense.. Each of the terrestrial planets consists of a dense iron-rich core surrounded by a rocky mantle, composed largely of magnesium and iron silicates
The density of each planet provides information about the relative sizes of the iron-rich core and the rocky mantle and crust, since the metallic core is much denser than the rocky components. Mercury’s uncompressed density (what its density would be without compaction of its interior by the planet’s own gravity) is about 5.3 grams per cubic centimeter, by far the highest of all the terrestrial planets
There are three major theories to explain why Mercury is so much denser and more metal-rich than Earth, Venus, and Mars. Each theory predicts a different composition for the rocks on Mercury’s surface
Terrestrial planet compositions controlled by accretion disk magnetic field – Progress in Earth and Planetary Science [15]
Terrestrial planet compositions controlled by accretion disk magnetic field. Progress in Earth and Planetary Science volume 8, Article number: 39 (2021)
Each layer has different dominant elements (e.g., increasing iron content with depth and increasing oxygen content to the surface). Chondrites, the building blocks of the terrestrial planets, have mass and atomic proportions of oxygen, iron, magnesium, and silicon totaling ≥ 90% and variable Mg/Si (∼ 25%), Fe/Si (factor of ≥2), and Fe/O (factor of ≥ 3)
Here we predict terrestrial planet compositions and show that their core mass fractions and uncompressed densities correlate with their heliocentric distance, and follow a simple model of the magnetic field strength in the protoplanetary disk. Our model assesses the distribution of iron in terms of increasing oxidation state, aerodynamics, and a decreasing magnetic field strength outward from the Sun, leading to decreasing core size of the terrestrial planets with radial distance
