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.

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.

How is Jupiter’s surface?

Surface. As a gas giant Jupiter doesn’t have a true surface. The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter it wouldn’t be able to fly through unscathed either.

used to measure distance between objects and in solar system. One AU spans a distance of about 150 million kilometers. Scientists have used satellites and space probes to measure this unit. Mercury is about 0.4 AU from the sun.

When did Olympus Mons erupt?

25 million years ago

By some estimates the most recent large volcanic eruption at Olympus Mons occurred only 25 million years ago. The oldest activity at Olympus Mons could be much older than this and would have been buried by younger lava flows. The caldera of Olympus Mons is the depression near the top center of the image.

Is Mercury’s surface heavily cratered?

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.

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.

What does the planet Mercury do?

Mercury’s magnetic field is strong enough to deflect the solar wind around the planet creating a magnetosphere. The planet’s magnetosphere though small enough to fit within Earth is strong enough to trap solar wind plasma. This contributes to the space weathering of the planet’s surface.
