Earthquake and volcano worksheet Crossword - WordMint - Free Printable

To solve the crossword puzzle, we need to match the clues with the correct terms related to earthquakes and volcanoes. Here are the solutions along with explanations:

Across

1. 2. Is the mountain that forms when molten rock called magma is forced to the earth surface
- Answer: Volcano
- Explanation: A volcano is a landform where magma (molten rock) erupts onto the Earth's surface.

2. 4. Is the study of earthquakes
- Answer: Seismology
- Explanation: Seismology is the scientific study of earthquakes and seismic waves.

3. 6. Is the sudden return of elastically deformed rock to its original shape
- Answer: Elastic rebound
- Explanation: Elastic rebound is the theory that explains how rocks store energy during an earthquake and then release it suddenly.

4. 9. A funnel-shaped pit around the central vent of a volcano
- Answer: Caldera
- Explanation: A caldera is a large, basin-shaped depression formed by the collapse of land following a volcanic eruption.

5. 11. Is magma that flows onto the earth surface
- Answer: Lava
- Explanation: Lava is molten rock that has erupted onto the Earth's surface.

6. 13. Is the change in the shape of in response to stress
- Answer: Deformation
- Explanation: Deformation refers to the change in shape or size of rocks due to stress.

7. 14. Is a tracing of earthquake motion created by seismograph
- Answer: Seismogram
- Explanation: A seismogram is a graphical record of ground motion produced by a seismograph.

Down

1. 1. Sometimes referred to as stratovolcanoes are on the most common type of volcanoes
- Answer: Composite volcano
- Explanation: Composite volcanoes, also known as stratovolcanoes, are steep-sided volcanoes composed of alternating layers of lava, ash, and other volcanic materials.

2. 3. Are built out of layers of lava from repeated nonexplosive eruptions
- Answer: Shield volcano
- Explanation: Shield volcanoes are broad, gently sloping volcanoes built up from many layers of fluid lava.

3. 5. Is the break in the earth's crust along which blocks of the crust slide relative to one another
- Answer: Fault
- Explanation: A fault is a fracture in the Earth's crust where movement occurs.

4. 7. Or shear wave are the second fastest seismic waves
- Answer: S-wave
- Explanation: S-waves (secondary waves) are shear waves that travel through the Earth's interior and are slower than P-waves but faster than surface waves.

5. 8. A circular depression that forms when a magma chamber empties and causes the ground above to sink
- Answer: Caldera
- Explanation: A caldera is a large, basin-shaped depression formed by the collapse of land following a volcanic eruption.

6. 10. Which travel through solids liquids and gases are the fastest seismic waves
- Answer: P-wave
- Explanation: P-waves (primary waves) are compressional waves that travel faster than S-waves and surface waves.

7. 12. Is the point on the earth surface directly above an earthquake starting point
- Answer: Epicenter
- Explanation: The epicenter is the point on the Earth's surface directly above the focus (hypocenter) of an earthquake.

8. 15. Are small volcanic cone made entirely of pyroclastic material
- Answer: Cinder cone
- Explanation: Cinder cones are small, steep volcanoes composed almost entirely of loose pyroclastic fragments.

9. 16. Are wave of energy that travel through the earth
- Answer: Seismic waves
- Explanation: Seismic waves are waves of energy that travel through the Earth during an earthquake.

10. 17. Are instrument located at or near the surface of the earth
- Answer: Seismometer
- Explanation: A seismometer is an instrument used to detect and measure seismic waves.
