Geology Chapter 1

What is geology?

• Study of life on Earth

• Study of the universe

• Study of the Earth's composition and natural phenomena

How does geology contribute to studying other planets?

• By providing a framework for understanding other planets

• By studying the behavior of animals on other planets

• By studying the history of human civilization on other planets

Organize these options into the right categories

Groups:

(a) Uniformitarianism

,

(b) catastrophism

,

(c) operational geology

,

(d) historical geology

• long periods of no change

• belief that earth is older than the timeline in the bible

• belief that one or only a few castatrophic events shaped the earth's surface

• depends on a scientist's worldview because their models of Earth's history are different

• belief that earth-forming prcesses are natural, always the same

• slow geologic process

• Important for obeying the Creation Mandate

• observations help geologist to learn about the Earth

• belief that earth-forming processes always happen at the same gradulat rate

(c) inner core

,

(d) outer core

• outer most layer

• extremely hot and dense

• inner most layer

• alot of pressure

• solid iron and nickel

• made of continental crust and oceanic crust

• helps create earth's magnetic field

• moves with tectonic plates

• solid

• largest layer of earth's volume

• Solid and Liquid

• Contains the asthenosphere

• 100% liquid iron and nickel

• thicker under continetal crust

Where is the Moho?

• between the inner and outer core

• between the outer core and the mantle

• between the mantle and crust

• between the continental and oceanic crust

The lithosphere is part of the

• crust and upper mantle

• asthenosphere and crust

• crust and outer core

• inner core and moho

As you go deeper into the earth what happens?

• Pressure decreases and temperature increases

• pressure increases and temperature decreases

• pressure increases and temperature increases

• pressure decreases and temperature decreases

Select ALL that the study of tectonics studies.

• earth shaping process and the structures they form

• earthquakes

• volcanos

• mountains

What is it called when oceanic plates slide under continental plates.

• duction

• subduction

• deduction

• subplates

A hypothesis is _________________________

• a tentative explanation for some observed phenomena that is the starting point for further investigation

• a well-tested and generally accepted explanation for some observed natural phenomena

• a statement or description of some observed natural phenomena that appears always to be true

• a standard model of some sort used to describe everyday occurrences
