Plate Tectonics & boundaries Review Quiz 2025

What is sea-floor spreading?

• The process by which new oceanic crust is created at mid-ocean ridges.

• The movement of tectonic plates away from each other.

• The erosion of oceanic crust due to wave action.

• The formation of underwater volcanoes from tectonic activity.

What is a deep-ocean trench?

• A deep valley in the ocean floor.

• A shallow area of the ocean.

• A type of underwater volcano.

• A region with high ocean temperatures.

What is a convergent boundary?

• A boundary where two tectonic plates collide.

• A boundary where two tectonic plates move apart.

• A boundary where tectonic plates slide past each other.

• A boundary that forms when tectonic plates are stationary.

What are fossils used for in geology?

• To understand the history of life and the age of rock layers.

• To determine the chemical composition of rocks.

• To predict future geological events.

• To measure the temperature of the Earth's core.

The preserved remains or traces of living things are called?

• Fossil

• Artifact

• Relic

• Specimen

What is subduction?

• The process where one tectonic plate moves under another plate.

• The process where two tectonic plates collide and push upwards.

• The process of tectonic plates sliding past each other horizontally.

• The process where tectonic plates break apart and create new crust.

What is a fault?

• A fracture in the Earth's crust where blocks of rock have moved.

• A type of rock formation that is completely solid.

• A geological feature that only occurs underwater.

• A process of erosion caused by wind.

What is a tectonic plate?

• Large sections of the Earth's lithosphere that move and interact with each other.

• Small fragments of the Earth's crust that float on the surface of the ocean.

• Layers of soil that are formed by weathering and erosion.

• Solid rocks that are found deep within the Earth's mantle.

What type of boundary is most associated with earthquakes?

• Divergent boundary

• Convergent boundary

• Transform boundary

• Subduction boundary

What is the lithosphere?

• The rigid outer layer of the Earth, consisting of the crust and upper mantle.

• The inner core of the Earth, made up of molten iron and nickel.

• The layer of the Earth that is primarily composed of water and ice.

• The gaseous envelope surrounding the Earth, known as the atmosphere.
