Re: Geology Multiple Choice Exam

Feel free I will get the Multiple Choice Questions on Introduction to Geology - Chapter 1 so that you can check it easily.

Here are some questions for you

Which of the following statements regarding the scientific methods is true?

A hypothesis must be agreed upon by more than one scientist
A theory is a hypothesis that has withstood many scientific tests
A theory is proven to be true, and therefore may not be discarded
A hypothesis cannot predict the outcome of scientific experiments

According to the principle of uniformatarianism,

geologic processes we observe today have operated in the past
geologic process in the past operated at the same rate as they do today
all of the planets formed from a uniform solar nebula
early Earth was covered by a uniform magma ocean

Approximately how long ago did the Big Bang take place?

10-15 thousand years ago
10-15 million years ago

nuclear fusion
nuclear fission
metamorphism
convection

What are the two most abundant elements in nebula (gas clouds) in the universe?

oxygen and silicon
hydrogen and helium
iron and nickel

The process by which an originally homogeneous Earth developed a dense core and a light crust is called:

differentiation
accretion
compression

The heat that caused melting in the Earth's early history was supplied from which of the following events or causes?

Minerals:

can form by life-processes -- organic
