8th Grade Earth and Space Science - Mock STAAR Review2

Front

What causes winter in North America?

Back

Winter occurs in North America when the Earth is tilted away from the Sun, resulting in less direct sunlight.

Front

What is the new moon phase?

Back

The new moon phase is when the Moon is positioned between the Earth and the Sun, making it invisible from Earth.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often creating new crust as magma rises.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, leading to one plate being forced below the other, often causing earthquakes and volcanic activity.

Front

What is a nebula?

Back

A nebula is a large cloud of dust and gas in space, often the birthplace of stars.

Front

What is the significance of the tilt of the Earth?

Back

The tilt of the Earth affects the seasons; different hemispheres receive varying amounts of sunlight throughout the year.

Front

What is the full moon phase?

Back

The full moon phase occurs when the Earth is between the Sun and the Moon, allowing the entire face of the Moon to be illuminated.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally, often causing earthquakes.

Front

What is the role of gravity in the formation of celestial bodies?

Back

Gravity pulls together gas and dust in space to form stars, planets, and other celestial bodies.

Front

What is the difference between a galaxy and a supercluster?

Back

A galaxy is a collection of stars, gas, and dust bound together by gravity, while a supercluster is a large group of galaxies.
