Grade 7 Geography Quiz

What are the environmental effects of earthquakes?

• Air pollution

• Landslides, tsunamis, soil liquefaction, and damage to infrastructure

• Deforestation

• Global warming

How do earthquakes impact the ecosystem?

• Earthquakes have no impact on the ecosystem

• Earthquakes can disrupt the balance of ecosystems by causing landslides, tsunamis, and changes in the landscape.

• Earthquakes make the ecosystem more stable

• Earthquakes help the ecosystem by providing nutrients

What are the causes of earthquakes?

• Sudden release of energy in the Earth's crust

• Global warming

• Tectonic plate movement

• Volcanic eruption

How does the movement of tectonic plates cause earthquakes?

• The movement of tectonic plates causes stress to build up in the Earth's crust, which is released as seismic energy during an earthquake.

• The movement of tectonic plates has no effect on earthquakes

• Earthquakes are caused by volcanic eruptions, not tectonic plate movement

• Earthquakes are simply random events and not related to tectonic plate movement

What is the impact of plate tectonics on landforms?

• Plate tectonics create new animal species

• Plate tectonics can create mountains, valleys, and other landforms.

• Plate tectonics only affect the ocean floor

• Plate tectonics have no impact on landforms

Describe the impact of volcanic eruptions on the environment.

• Volcanic eruptions have a positive impact on vegetation

• Volcanic eruptions can release harmful gases, destroy vegetation, and alter landscapes.

• Volcanic eruptions create a healthier environment

• Volcanic eruptions have no impact on the environment
