Plate Tectonics TEST

Front

What is Plate Tectonics?

Back

The theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other, causing geological activity.

Front

What is sea-floor spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

Front

What is a composite volcano?

Back

A type of volcano characterized by a steep profile and explosive eruptions, formed from alternating layers of lava and ash.

Front

What is a shield volcano?

Back

A type of volcano with a broad, gently sloping shape, formed by the eruption of low-viscosity lava that can flow long distances.

Front

What is a cinder cone volcano?

Back

A small, steep-sided volcano formed from the accumulation of volcanic debris, such as ash and cinders.

Front

Where do most earthquakes occur?

Back

Most earthquakes occur along tectonic plate boundaries due to the movement and interaction of the plates.

Front

What is a seismograph?

Back

An instrument used to detect and record the intensity, duration, and direction of seismic waves from earthquakes.

Front

What is the Ring of Fire?

Back

A major area in the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur, due to tectonic plate boundaries.

Front

What is subduction?

Back

The process by which one tectonic plate moves under another plate and sinks into the mantle.
