Summative #6 Review- 7th Grade Science

Front

What is a Convergent Boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often causing one plate to be forced below the other, leading to mountain formation, earthquakes, and volcanic activity.

Front

What causes volcanoes to form at plate boundaries?

Back

Volcanoes form at plate boundaries when one tectonic plate goes under another, melting into magma, and at hot spots where there is increased heat to melt rock.

Front

How do volcanoes form at Divergent Plate Boundaries?

Back

Volcanoes form at divergent plate boundaries when two tectonic plates move away from each other, allowing magma from the mantle to rise, fill the gap, and harden.

Front

What happens at a Divergent Plate Boundary?

Back

At a divergent plate boundary, tectonic plates move apart, and magma from the mantle fills the crack, solidifying to form new crust.

Front

What are some hazards associated with fault lines?

Back

Hazards associated with fault lines include earthquakes and tension, which can lead to significant geological activity.

Front

What is a Hot Spot?

Back

A hot spot is a location where magma from deep within the Earth's mantle rises to the surface, often creating volcanoes independent of tectonic plate boundaries.

Front

What is the difference between a Transform Boundary and a Convergent Boundary?

Back

A transform boundary is where two plates slide past each other, causing earthquakes, while a convergent boundary is where two plates collide, leading to mountain building and volcanic activity.

Front

What is magma?

Back

Magma is molten rock located beneath the Earth's surface that can rise to form volcanoes when it erupts.

Front

What is the role of tectonic plates in earthquakes?

Back

Tectonic plates move and interact at their boundaries, and when they become stuck, stress builds up until it is released as an earthquake.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur due to tectonic plate movements.
