Geology Flashcard

Front

What are the sources of energy that drive the rock cycle?

Back

Solar energy, weather and geothermal energy

Front

What are convection currents in the Mantle and how do they change the Earth's surface over time?

Back

They are circular movements of molten rock that cause tectonic plates to move, leading to changes like earthquakes and mountain formation over millions of years.

Front

Which layer of the Earth is involved in the movement of tectonic plates through convection?

Back

Mantle

Front

How is the geological time scale used to organize Earth’s history?

Back

By categorizing Earth's history into eons, eras, periods, and epochs based on significant events and changes.

Front

Which rock forms from compaction and cementation?

Back

Sedimentary rock

Front

Which rock forms from melting and solidifying?

Back

Igneous rock

Front

Which of the following best describes a geologic process?

Back

A natural mechanism that shapes the Earth's surface

Front

The lithosphere is broken up into pieces we call

Back

tectonic plates

Front

Convection currents happen in the _____ and heat that drives them comes from the _____.

Back

mantle, core

Front

Law of Superposition

Back

A principle stating that in any sequence of undisturbed layers of sedimentary rock, the oldest layer is at the bottom and layers above it are progressively younger.
