What is the name of the features on Mercury’s surface caused by the buckling from contraction as the core solidifies?
They are long sinuous cliffs called lobate scarps. These scarps appear to be the surface expression of thrust faults where the crust is broken along an inclined plane and pushed upward. What caused Mercury’s crust to shrink? As the interior of the planet cooled it contracted.

What are landmarks on Mercury?
One of the most notable features on Mercury is Caloris Basin an impact crater about 960 miles wide that formed early in the planet’s history. Mercury has no rings no moons and a relatively weak magnetic field. Mercury is a scarred world covered in craters ridges and bright debris from numerous impacts.
What is surface of Mercury?
Mercury’s surface resembles that of Earth’s Moon scarred by many impact craters resulting from collisions with meteoroids and comets. Craters and features on Mercury are named after famous deceased artists musicians or authors including children’s author Dr. Seuss and dance pioneer Alvin Ailey.
What caused Mercury’s craters?
Mercury’s impact craters were made early in the evolution of the solar system nearly 4 billion years ago by meteorites which hit the surface. The relatively smooth plains between craters indicates that at one point the surface was probably volcanic as lava flows filled in after the impacts of large objects.

Mercury and the Moon
Impact craters dominate the surfaces of Mercury and the Earth’s Moon. Both bodies lack liquid water on their surfaces that would erode impact craters over time. They also lack an atmosphere which on planets like the Earth and Venus could disintegrate meteoroids before they impact the surface.

The planet Venus sometimes called the “evening star” or “morning star ” is the second-brightest object in the night sky — only the Moon is brighter. Jupiter Mars and Saturn often are visible later at night than Venus.
Which statement best explains why the Moon has more craters than Earth?
Because of tectonics the surface of Earth is recycled many times throughout its long history. As a result very few rocks on Earth are as old as the rocks on the Moon. The Moon has not had tectonics for billions of years. That’s a lot more time for craters to form and stay put.
