Earth Science Semester 1 Exam Review

Front

What is a high mass star's evolution after the main sequence?

Back

A high mass star becomes a supergiant after the main sequence.

Front

What is the explosion that occurs at the end of a massive star’s life called?

Back

The explosion is called a supernova.

Front

How does distance affect gravitational force between two planets?

Back

The farther away two planets are, the less the gravitational force between them.

Front

What does a Doppler blue shift indicate about a star's movement?

Back

A Doppler blue shift indicates that the star is moving toward us.

Front

How does the distance of a planet from the sun affect its orbital period?

Back

The farther away a planet is from the sun, the longer it takes to orbit the sun once.

Front

Define a supernova.

Back

A supernova is a powerful and luminous explosion that occurs at the end of a massive star's life.

Front

What is a black dwarf?

Back

A black dwarf is a theoretical stellar remnant that forms when a white dwarf cools down and no longer emits significant heat or light.

Front

What is a protostar?

Back

A protostar is an early stage in the formation of a star, where gas and dust collapse under gravity.

Front

What is a red giant?

Back

A red giant is a late stage in the life cycle of a star, characterized by expansion and cooling after hydrogen in the core is depleted.

Front

What is the relationship between mass and gravitational force?

Back

The greater the mass of two objects, the stronger the gravitational force between them.
