Why is the crater important?
The Planetary Deep Past Impact craters allow scientists to study a planet’s geological history—even when the records are buried beneath the surface. Rocks ejected by impacts contain minerals that formed in the presence of liquid water; some craters also show signs of ancient lakes.
What is the biggest crater on the moon?
South Pole-Aitken basin
What is the deepest crater?
Stretching 1,550 miles (2,500 kilometers) wide and 8 miles (13 km) deep, the South Pole-Aitken basin, as the tremendous hole is known to Earthlings, is the oldest and deepest crater on the moon, and one of the largest craters in the entire solar system.
What is the deepest crater on Earth?
Vredefort crater
Does the dark side of the moon have craters?
The far side has far fewer ‘maria’, which are large dark patches caused by ancient volcanic flows. Instead it is much more densely covered with craters compared to the near side. While the Earth and Moon were forming, heat from the still-molten Earth slowed the cooling process of the near side of the Moon.
Which side of the moon is thinner?
Only 1% of the surface of the far side is covered by maria, compared to 31.2% on the near side. According to research analyzed by NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, the reason for the difference is because the Moon’s crust is thinner on the near side compared to the far side.
Which side of the moon is thicker?
This video states that NASA has determined that the far side of the moon’s crust is thicker than the near side’s crust.
Why is life not possible on all planets Class 6?
The Earth is the only planet where conditions are favourable to support life. It is neither too hot nor too cold and thus have an optimum temperature to support human existence. It has water and air, which very much essential for the survival of humans.
Which plant is known as Earth’s twin planet?
Venus has approximately the same mass as the Earth yet it is a hellish place where surface temperatures are over 400°C and the surface pressure is a hundred times that on Earth. The key to understanding Venus lies in its atmosphere.
Which planet is known as Earth’s twin?
Venus
Who is the sister of Earth?
How does Venus look like?
From space, Venus is bright white because it is covered with clouds that reflect and scatter sunlight. At the surface, the rocks are different shades of grey, like rocks on Earth, but the thick atmosphere filters the sunlight so that everything would look orange if you were standing on Venus.
