Exploring Plate Tectonics

What is the primary cause of earthquakes?

• Volcanic eruptions

• Movement of tectonic plates along faults

• Meteorite impacts

• Tsunamis

Define a fault in geological terms.

• A fault is a type of rock formation.

• A fault is a layer of sedimentary rock.

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

• A fault is a volcanic eruption.

What type of fault occurs when two blocks of crust slide past each other?

• Transform fault

• Normal fault

• Thrust fault

• Reverse fault

What is the Richter scale used for?

• The Richter scale is used to measure the magnitude of earthquakes.

• To evaluate the strength of tornadoes.

• To assess the depth of ocean trenches.

• To measure the temperature of volcanoes.

How do seismic waves help scientists study the Earth's interior?

• Seismic waves help in determining the age of rocks on the surface.

• Seismic waves are used to measure ocean currents and tides.

• Seismic waves help scientists study the Earth's interior by revealing information about its composition and structure through their speed and behavior.

• Seismic waves can predict weather patterns in the atmosphere.

What is the difference between a focus and an epicenter of an earthquake?

• The focus is the point where seismic waves are generated, and the epicenter is the location of the fault line.

• The focus is where the earthquake is felt most strongly, and the epicenter is the origin.

• The focus is the underground point of origin, and the epicenter is the surface point directly above it.

• The focus is the surface point, and the epicenter is underground.

What are the three main types of plate boundaries?

• Subduction, Compression, Extension

• Lateral, Radial, Axial

• Fracture, Shear, Tension

• Divergent, Convergent, Transform

How can volcanoes be formed at divergent plate boundaries?

• Volcanoes form when tectonic plates collide and create pressure.

• Volcanoes are formed at divergent plate boundaries due to the rising magma that fills the gap created by separating tectonic plates.

• Volcanoes arise from the cooling of magma deep within the Earth's crust.

• Volcanoes are created by the accumulation of sediment at plate boundaries.

What is the term for molten rock beneath the Earth's surface?

• magma

• igneous rock

• volcanic ash

• lava

What type of volcano is characterized by gentle slopes and low-viscosity lava?

• Cinder cone volcano

• Shield volcano

• Stratovolcano

• Lava dome volcano
