Front

What occurs in both fusion and fission reactions?

Back

Small amounts of matter are converted into large amounts of energy.

Front

What do the light waves of a galaxy that is moving TOWARD us look like?

Back

Blue shifted.

Front

Which processes change sedimentary rocks into metamorphic rocks?

Back

Temperature and pressure changes.

Front

What causes wavy bands of light and dark minerals in gneiss bedrock?

Back

Heat and pressure during metamorphism.

Front

What is a dark spot on the photosphere of the sun called?

Front

Define fusion in the context of nuclear reactions.

Back

Fusion is the process where light nuclei combine to form a heavier nucleus, releasing energy.

Front

Define fission in the context of nuclear reactions.

Back

Fission is the process where heavy nuclei split into lighter nuclei, releasing energy.

Front

What is the significance of blue shift in astronomy?

Back

Blue shift indicates that an object is moving toward the observer, causing its light waves to compress.

Front

What is the role of temperature and pressure in metamorphism?

Back

Temperature and pressure cause changes in mineral structure and composition, transforming sedimentary rocks into metamorphic rocks.

Front

What is a solar flare?

Back

A solar flare is a sudden eruption of intense high-energy radiation from the sun's surface.
