5.14 Boundaries and Hazards Quiz

Which statement about the formation of ocean trenches is true?

• Ocean trenches form in the middles of plates, far from boundaries.

• Ocean trenches form at plate boundaries.

• Ocean trenches form from weathering and erosion.

• Ocean trenches form along coral reefs.

Which statement about the formation of volcanoes is true?

• Volcanoes form at plate boundaries or at hot spots.

• Volcanoes only form in the middles of plates, far from boundaries.

• Volcanoes form from weathering and erosion.

• Volcanoes form randomly from changes in Earth's interior.

Which statement about the formation of earthquakes is true?

• Earthquakes form from underground weathering and erosion.

• Earthquakes always form in the middles of plates, far from boundaries.

• Earthquakes often form at plate boundaries.

• Earthquakes form randomly from changes in Earth's interior.

How do mountains form? Mountains tend to form ​ (a)   along the ​ (b)   of tectonic plates. Some of the steepest mountains form where two tectonic plates move toward each other at a ​ (c)  

• in ranges
• boundaries
• convergent

How do volcanoes form? Many volcanoes form at a convergent plate boundary between ​ (a)   . At this boundary, melted rock called ​ (b)   rises and forms a volcano. Other volcanoes form at ​ (c)   in the middles of plates.

• a land plate and an ocean plate
• magma
• hot spots

How does a severe earthquake affect the surface?

Drag and drop the statements to show the correct order of events during an earthquake.

• When the tension is too great, rocks break at the focus of the earthquake

• Seismic waves reach the surface and cause the ground to shake.

• Forces within Earth push or pull tectonic plates in different directions

• Energy spread outward from the focus in seismic waves

What hazards are caused by natural disasters?

Match the natural disaster to the hazard it causes.

• tsunami

• explosion of heated rock, ashes, and gases

• flood

• water spilling onto or flowing over land that is usually dry

• volcanic eruption

• severe shaking of the ground

• earthquake

• a huge ocean wave that washes over the coast

  
  

Severe earthquakes sometimes strike the state of California.

Which strategy is most effective for managing earthquakes in California?

• using artificial seismic waves to direct earthquakes to remote areas

• constructing houses and other buildings to withstand earthquakes

• using underground explosions to cause frequent, weak earthquakes

• digging tunnels along faults to prevent earthquakes

  digging tunnels along faults to prevent earthquakes

Volcanic eruptions can occur along the border of the Pacific Ocean and surrounding continents.

Which strategy is most effective for managing volcanic eruptions?

• digging tunnels inside volcanoes to prevent eruptions

• using underground explosions to cause the magma move away from the volcano

• using artificial seismic waves to stop the volcano from erupting

• planning to remove people from the area before the volcano erupts

Tsunamis can occur along the coastlines of oceans.

Which strategy is most effective for managing tsunamis?

• using artificial seismic waves to stop the tsunami from forming

• alerting people when an approaching tsunami is detected

• using underground explosions to break a tsunami into frequent, mild ocean waves

• digging tunnels underneath the ocean to prevent tsunamis
