Earthquakes & Earthquake waves

What is a reverse fault?

• A type of fault where two tectonic plates pull apart, causing rock to sink.

• A type of fault where two tectonic plates slide past each other horizontally.

• A type of fault where two tectonic plates push together, forcing rock upward.

• A type of fault that occurs when rocks break due to tension, causing a vertical drop.

What is a tectonic plate?

• A large section of the Earth's crust that moves and interacts with other plates.

• A type of rock found in the Earth's mantle.

• A layer of water that covers the Earth's surface.

• A small fragment of the Earth's atmosphere.

What is a fault line?

• A fracture in the Earth's crust along which movement has occurred.

• A type of geological formation that is always stable.

• A line that indicates the boundary between two tectonic plates.

• A crack in the Earth's surface that does not move.

What is the difference between the focus and the epicenter?

• The focus is the point inside the Earth where the earthquake starts, while the epicenter is the point directly above it on the surface.

• The focus is the point on the surface where the earthquake is felt, while the epicenter is the point inside the Earth where it starts.

• The focus is the location of the strongest seismic waves, while the epicenter is the point where the earthquake is first detected.

• The focus is the point where tectonic plates meet, while the epicenter is the point where the earthquake ends.

What is a normal fault?

• A fault where the rock above the fault moves down relative to the rock below.

• A fault where the rock above the fault moves up relative to the rock below.

• A fault that does not involve any movement of rock layers.

• A fault that occurs only in volcanic regions.

What is a strike-slip fault?

• A fault where two tectonic plates slide past each other with little up or down movement.

• A fault that causes one tectonic plate to be pushed over another.

• A fault that results in the formation of mountains due to compression.

• A fault that occurs when tectonic plates move away from each other.

What is the role of plate boundaries in earthquakes?

• Most earthquakes occur along plate boundaries where plates interact, causing stress and movement.

• Plate boundaries are areas where no earthquakes occur.

• Earthquakes are caused by volcanic activity, not plate boundaries.

• Plate boundaries are only relevant to the formation of mountains.

What is the magnitude of an earthquake?

• A measure of the energy released during an earthquake.

• The depth at which the earthquake occurs.

• The distance from the epicenter to the nearest city.

• The duration of the earthquake's shaking.

What is the focus of an earthquake?

• The point within the Earth where an earthquake originates.

• The location on the Earth's surface directly above the earthquake.

• The area where seismic waves are first detected.

• The point where tectonic plates meet.

What is compression in geology?

• A type of stress that pulls rocks apart, causing them to fracture.

• A type of stress that pushes rocks together, causing them to fold or break.

• A process that involves the melting of rocks under extreme heat.

• A method of measuring the density of geological materials.
