Unit 7 Test

Front

What are tectonic plates?

Back

Tectonic plates are large pieces of the Earth's crust that move and interact with each other, causing geological activity such as earthquakes and volcanic eruptions.

Front

What does the term 'tsunami' mean?

Back

The term 'tsunami' comes from the Japanese word meaning 'harbor wave', referring to the large ocean waves that can cause destruction when they reach coastal areas.

Front

What is the most abundant element in the Earth's crust?

Back

Oxygen is the most abundant element in the Earth's crust by mass.

Front

What is a hot spot in geology?

Back

A hot spot is an area of volcanic activity that develops above where magma rises in a plume from the mantle, independent of tectonic plate boundaries.

Front

What evidence supports the theory of continental drift?

Back

Fossils of the same plants and animals found on different continents suggest that these continents were once connected.

Front

What is the significance of the theory of plate tectonics?

Back

The theory of plate tectonics explains the movement of the Earth's plates and how this movement causes earthquakes, volcanic activity, and the formation of mountains.

Front

What are the three types of plate boundaries?

Back

The three types of plate boundaries are divergent (plates move apart), convergent (plates collide), and transform (plates slide past each other).

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often creating deep ocean trenches.

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.

Front

What role do fossils play in understanding Earth's history?

Back

Fossils provide evidence of past life forms and help scientists understand the evolution of species and the geological history of Earth.
