Chapter 11: Problem 79

If you could examine rock samples from the surface of Venus, would you expect them to be the same as rock samples from Earth? Would you expect to find igneous, sedimentary, and metamorphic rocks like those found on Earth (see Section 9-3)? Explain your answers.

Short Answer

Expert verified
No, rock samples from Venus would not be exactly the same as those from Earth. It's highly likely to only find igneous and some sort of metamorphic rocks in Venus due to its harsh conditions. Sedimentary rocks are likely non existent as they require presence of liquid water, which is not available on Venus.

Step by step solution

01

Understanding the Composition of Rocks on Earth

On Earth, there are three main types of rocks: igneous, sedimentary and metamorphic. Igneous rocks form when melted rock (magma) cools and solidifies. Sedimentary rocks are formed over time from erosion or deposition of other rocks or organisms. Metamorphic rocks are sedimentary or igneous rocks that have been transformed by extreme heat and pressure.
02

Understanding the Environment of Venus

Venus is the second planet from the Sun and is known for its extremely high surface temperatures, pressure and lack of water. These conditions are not conducive for the formation of sedimentary rocks, which require water for weathering and erosion processes, and deposition of organic matter.
03

Comparing the Two Environments

Considering the conditions on Venus, it's unlikely we would find sedimentary rocks as the process of sedimentation requires presence of liquid water. However, the high temperatures and pressures present on Venus might allow for the existence of only igneous and some sort of metamorphic rocks.

What kind of surface features are found on Mercury? How do they compare to surface features on the Moon? Why are they probably much older than most surface features on the Earth?

The total cost of the Mars Global Surveyor mission was about \(\$ 154\) million. (To put this number into perspective, in 2000 the U.S. Mint spent about \(\$ 40\) million to advertise its new \(\$ 1\) coin, which failed to be accepted by the public. Several recent Hollywood movies have had larger budgets than Mars Global Surveyor.) Does this expenditure seem reasonable to you? Why or why not?
