Answer:
From left to right, they are Mercury, Venus, Earth, and Mars. Unlike the outer planets, which have many satellites, Mercury and Venus do not have moons, Earth has one, and Mars has two. Of course, the inner planets have shorter orbits around the Sun, and they all spin more slowly. The terrestrial planets are rich in heavier gases and gaseous compounds, such as carbon dioxide, nitrogen, oxygen, ozone, and argon. In contrast, the gas giant atmospheres are composed mostly of hydrogen and helium. The atmospheres of at least the inner planets have evolved since they formed.
Explanation: Hope this helps
Answer:
Base on earth's structure, process and geologic history.
Explanation:
There are various planets in outer space that are considered analogous to that of earth or the Earth-like the planet like <u>Kepler-22b. Kepler-69c. Kepler-62f and Kepler-452b</u>. These Earth-like planets are called as G and K stars. like venus which is considered a twin of earth. These planets are considered to be 50% like earth but differ based on temperature and Terraforming is going to be what might be influencing the future of the explorations. Which is a hypothetical process of deliberating modifying the atmospheric conditions to make it habitable for man.
Answer:
- Shape of the continents
- Fossils of the same species found on continents that are not connected
- Evidence of ice sheets in places that are hot in the present
- Mid-ocean ridges
Explanation:
The continental drift theory is a theory that suggests that the continents are always on the move, thus they change their shape, location, collide with each other, move away from each other etc.
The shape of South America and Africa is one of the evidences. If the shapes of the continents are taken out of a map, and the eastern coast of South America and western coast of Africa are merged, they fit in perfectly.
There are numerous fossils of the same species of animals and plants that have been found all over the world, even though the continents are isolated and separated by water bodies.
In some places that are very hot in the presence, like South Africa, have evidence of ice sheets. In the current conditions that is simply not possible considering that the temperature in this part of the world goes well over 40 C degrees.
The mid-ocean ridges are very nice proof of the continental drift theory. They are one of the evidence that can be observed in the present, where new crust is constantly forming and pilling up, while pushing the old crust sideways further away from it.
Continental
Oceanic
Mantle
Outter core
inner core
The answer is the second one
