Geology Questions and Answers
What percent of the earth is land and how much is water?
Why is the interior of the earth very hot?
What human activities can increase the rate of weathering?
Assume that parcel of air at the surface has a temperature of 29 degree C and a relative humidity of 50%. If the parcel rises, at what altitude should clouds begin to form? I can't find any kind of formula in the textbook to figure this out. All the figures in the book show the condensation point is 2000m, but that doesn't sound right with the humidity value already so high at the surface.
What is the main type of energy used to help convert metamorphic rocks into ingneous rocks in the rock cycle ?
Calculate the rate of the Pacific Plate's motion in cm per year for the island sequence Kauai to Oahu. Can you show me the steps. Note that one kilometer is the same as 100,000 cm. Island Sequences Separation Distance Average Difference a. Kauai to Oahu 181 km 2,100,000 years

Most geologic events happened very slowly. Name two geologic events- one land building and one erosional- that happen fast enough for people to see.
Did the breakup of Pangaea during the Jurassic Period led to the extinction of some dinosaurs and the evolution of other dinosaurs?

Why is it important to study rocks?
What is an example of a continental divergent boundary?
What percentage of land on earth is desert? I don't just want to know the largest desert but exactly how much of the earth's land surface is comprised of desert.

How does convection cause tectonic plates to move?
Has there been more than one Pangaea? Since Pangea began to separate only 200 million years ago, and the Earth is about 4.5 billion years old, do the land masses periodically merge into a supercontinent and then break apart again? If so, how many times has this happened? If not, why did it only happen once? At their current trajectories, won't the continents smash back into each other?
Consider the following statements made by two students debating why the oceanic and continental plates move: Student 1: The plates are moving because the mantle material is constantly moving beneath Earth’s plates, and this causes the plates to move.Student 2: I disagree. The plates are just floating on the mantle material. The plates stared moving a long time ago when Earth initially formed and the plates’ momentum keeps them moving toward each other.Do you agree or disagree with either or both of the students?A. I disagree with both students B. I agree with Student 1 C. I agree with Student 2 D. I agree with both students
