Earthquakes!

What are P Waves?

• Secondary waves that arrive after S waves during an earthquake.

• Primary waves that are the first to arrive during an earthquake.

• Surface waves that cause the most damage during an earthquake.

• Waves that travel through the Earth's core and are not detected on the surface.

What is tectonic plate movement?

• The shifting of the Earth's plates that can cause earthquakes.

• The movement of water in oceans and seas.

• The rotation of the Earth around its axis.

• The process of erosion caused by wind and water.

What is a seismic wave?

• A wave of energy that travels through the Earth, typically caused by an earthquake.

• A type of wave that only travels through water bodies.

• A sound wave produced by volcanic eruptions.

• A wave that can only be detected by animals.

What is a fault line?

• A type of geological formation where minerals are extracted.

• A fracture in the Earth's crust where blocks of land have moved past each other.

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

• A visual representation of seismic activity in an area.

What does the 'S' in 'S-waves' stand for?

• Surface

• Seismic

• Secondary

• Sonic

What is the Ring of Fire?

• A path along plate boundaries where volcanoes and earthquakes are common.

• A type of jewelry worn by ancient civilizations.

• A geographical area known for its dense forests and wildlife.

• A term used to describe a specific type of ocean current.

What is the difference between magnitude and intensity?

• Magnitude measures the energy released at the source, while intensity measures the effects of an earthquake at different locations.

• Magnitude is a measure of the depth of an earthquake, while intensity measures the height of the earthquake waves.

• Magnitude is the total damage caused by an earthquake, while intensity is the distance from the epicenter.

• Magnitude measures the duration of an earthquake, while intensity measures the frequency of the seismic waves.

What is a tsunami?

• A large ocean wave caused by underwater earthquakes or volcanic eruptions.

• A type of tidal wave caused by the gravitational pull of the moon.

• A storm surge caused by hurricanes and tropical storms.

• A phenomenon where the ocean water recedes suddenly before a wave hits.

What is a seismograph?

• A device that measures temperature changes in the earth's crust.

• A machine used to record the vibrations caused by earthquakes.

• An instrument that detects and measures atmospheric pressure.

• A tool for analyzing soil composition.

What causes earthquakes?

• Volcanic eruptions.

• Tectonic plate movement.

• Meteor impacts.

• Human activities such as mining.
