Earth Science Exam Review

Front

Fossils are usually found in _________ rock.

Back

Sedimentary rock is where fossils are typically found because it forms in layers and can preserve organic material.

Front

In which area of the sun does gas rise as it heats up, then fall back down as it cools?

Back

The convection zone is the area of the sun where gas rises when heated and falls when cooled.

Front

Which mineral property is illustrated by the peeling of muscovite mica into thin, flat sheets?

Back

Cleavage is the mineral property that allows muscovite mica to peel into thin, flat sheets.

Front

Identify part 8: sunspot, solar flare, granules, radiation zone.

Back

Granules are small, bright features on the sun's surface that indicate convection currents.

Front

Label Part 2: #2 Core, #2 Radiation zone, #2 Convection zone, #2 Corona.

Back

#2 Radiation zone is the layer of the sun where energy is transferred outward by radiation.

Front

What is the definition of sedimentary rock?

Back

Sedimentary rock is formed by the accumulation and compaction of mineral and organic particles.

Front

What is the role of the sun's core?

Back

The core is the innermost layer of the sun where nuclear fusion occurs, producing energy.

Front

Define the term 'solar flare'.

Back

A solar flare is a sudden eruption of energy on the sun's surface that can release a large amount of radiation.

Front

What is the difference between igneous and metamorphic rock?

Back

Igneous rock forms from cooled magma or lava, while metamorphic rock forms from existing rock that has been changed by heat and pressure.

Front

What does the term 'luster' refer to in minerals?

Back

Luster describes how light reflects off the surface of a mineral, indicating its shine.
