Plate Tectonics and Tectonic Activity

What are the three main types of plate boundaries?

• North, South, East

• Solid, Liquid, Gas

• Hot, Cold, Warm

• Divergent, Convergent, Transform

What causes earthquakes to occur?

• Movement of the moon

• Sudden release of energy in the Earth's crust

• Global warming

• Volcanic eruptions

How do volcanic eruptions occur?

• Volcanic eruptions occur when the Earth's crust expands due to excessive heat, causing the release of lava and gases.

• Volcanic eruptions are caused by the impact of meteorites on the Earth's surface, leading to the release of magma and ash.

• Magma from within the Earth's mantle rises to the surface, causing pressure to build up and eventually leading to an explosive release of gases, ash, and lava.

• Volcanic eruptions occur when underground water comes into contact with hot rocks, causing a sudden release of steam and volcanic materials.

What are the effects of tectonic activity on the Earth's surface?

• It can cause earthquakes, volcanic eruptions, mountain formation, and the creation of ocean basins.

• It can cause tornadoes and hurricanes

• It can result in the melting of polar ice caps

• It can lead to the formation of deserts

What is the Ring of Fire and why is it significant?

• The Ring of Fire is a famous rock band known for their hit song 'Johnny Cash'.

• The Ring of Fire is a popular amusement park known for its roller coasters and water rides.

• The Ring of Fire is a fictional magical ring in a popular fantasy novel series.

• The Ring of Fire is a region in the Pacific Ocean basin known for its frequent earthquakes and volcanic eruptions.

What are seismic waves and how are they related to earthquakes?

• Seismic waves are a type of ocean wave and have no relation to earthquakes

• Seismic waves are caused by volcanic eruptions and have no relation to earthquakes

• Seismic waves are a form of sound waves and have no relation to earthquakes

• Seismic waves are waves of energy that travel through the Earth's layers, and they are related to earthquakes because they are the vibrations that are produced by the sudden release of energy in the Earth's crust.

Describe the process of subduction at convergent plate boundaries.

• Two tectonic plates move away from each other

• Tectonic plates slide past each other horizontally

• One tectonic plate is forced beneath another due to the difference in density.

• Tectonic plates collide and form a new plate boundary

Explain how divergent plate boundaries contribute to the formation of new crust.

• Magma from the mantle does not play a role in the formation of new crust at divergent plate boundaries.

• Divergent plate boundaries have no impact on the formation of new crust.

• At divergent plate boundaries, tectonic plates move away from each other, allowing magma to rise from the mantle and solidify, forming new crust.

• At divergent plate boundaries, the plates move towards each other, causing the crust to break apart.

What are the different types of volcanic eruptions?

• Hot, warm, cold

• Lava, magma, ash

• Slow, medium, fast

• The different types of volcanic eruptions are effusive, explosive, and phreatic.

How do earthquakes and volcanic eruptions impact human societies and the environment?

• They can cause destruction of infrastructure, loss of life, displacement of populations, and environmental damage.

• They only cause minor inconveniences for human societies

• They have no impact on human societies and the environment

• They lead to improved infrastructure and environmental benefits
