8th Science Fall Semester Exam Review 2024

Front

What causes day and night on Earth?

Back

The rotation of the Earth on its axis causes different parts of the Earth to experience day and night as they move in and out of sunlight.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary occurs when two tectonic plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What evidence supports the theory of continental drift?

Back

Evidence includes the fit of the continents, matching fossil evidence across continents, and similar rock formations found in different regions.

Front

What is the role of gravity in a volcanic eruption?

Back

Gravity acts as an unbalanced force on rocks launched into the air during a volcanic eruption, pulling them back to the ground.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary occurs when two tectonic plates move towards each other, often resulting in one plate being forced beneath another.

Front

What is the difference between day and night?

Back

Day occurs when a location on Earth is facing the Sun, while night occurs when it is turned away from the Sun.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it causes rocks to continue moving until acted upon by another force.

Front

What is the significance of matching fossil evidence in supporting continental drift?

Back

Matching fossil evidence across continents suggests that these landmasses were once connected, supporting the idea of continental drift.

Front

What happens to rocks launched into the air during a volcanic eruption?

Back

Rocks are subjected to an unbalanced force of gravity, which eventually pulls them back to the ground after they are launched.

Front

What is a transform plate boundary?

Back

A transform plate boundary occurs when two tectonic plates slide past each other horizontally, often causing earthquakes.
