Question

Space probes discovered various geological features on Mars. Explain why scientists believe Mars has all three types of rock: igneous, metamorphic, and sedimentary.

a) Define the types of rocks present on Earth.
b) Discuss the evidence gathered from space probes.
c) Analyze the inference drawn about Mars' geology.
d) Explain the parallels drawn between Earth and Mars' rock formations.

Answer 1

Mars has all three types of rocks: igneous, metamorphic, and sedimentary, similar to Earth. The evidence from space probes and the examination of meteorites from Mars support this inference.

Step-by-step explanation:

Scientists believe Mars has all three types of rocks: igneous, metamorphic, and sedimentary. On Earth, igneous rocks form when magma or lava cools and solidifies, sedimentary rocks form when broken pieces of other rocks get cemented together, and metamorphic rocks are pre-existing rocks that are altered by heat and pressure. The evidence gathered from space probes, such as the examination of meteorites from Mars, has provided valuable information about the geological features on Mars' surface. Based on this evidence, scientists have inferred that Mars has all three types of rocks similar to Earth. They have drawn parallels between Earth and Mars' rock formations to understand the geological history of Mars.
