Plate Tectonic Theory and Earth's Features

What is Plate Tectonic Theory?

• Plate Tectonic Theory is a belief that the movement of tectonic plates is caused by the gravitational pull of the Moon.

• Plate Tectonic Theory is a scientific theory that explains how the Earth's lithosphere is divided into several large and small plates that move and interact with each other.

• Plate Tectonic Theory is a scientific theory that explains how the Earth's crust is made up of different types of rocks.

• Plate Tectonic Theory is a hypothesis that suggests the Earth's continents were once joined together in a supercontinent called Pangaea.

How are active volcanoes related to Plate Tectonic Theory?

• They are caused by earthquakes.

• They are formed by erosion.

• They occur at tectonic plate boundaries.

• They are unrelated to Plate Tectonic Theory.

Explain the distribution of earthquake epicenters in relation to Plate Tectonic Theory.

• Earthquake epicenters are primarily located in the middle of tectonic plates.

• Earthquake epicenters are primarily located along plate boundaries.

• Earthquake epicenters are randomly distributed across the globe.

• Earthquake epicenters are caused by volcanic activity rather than plate movements.

What are major mountain belts and how do they relate to Plate Tectonic Theory?

• Major mountain belts are formed by volcanic activity.

• Major mountain belts are formed by erosion.

• Major mountain belts are formed by the movement of glaciers.

• Major mountain belts are formed by the collision of tectonic plates as per the Plate Tectonic Theory.

Which tectonic plate boundaries are associated with the majority of active volcanoes?

• Convergent and divergent plate boundaries

• Subduction plate boundaries

• Transform plate boundaries

• Collision plate boundaries

How do convergent plate boundaries contribute to the formation of major mountain belts?

• Through subduction and volcanic activity

• Through erosion and weathering

• Through tectonic uplift and folding

• Through deposition and sedimentation

What type of plate boundary is responsible for the occurrence of most earthquakes?

• convergent plate boundary

• divergent plate boundary

• subduction zone

• transform plate boundary

Describe the relationship between subduction zones and the distribution of earthquake epicenters.

• Subduction zones are associated with the distribution of earthquake epicenters.

• Earthquake epicenters are evenly distributed across all types of tectonic boundaries.

• Subduction zones only cause volcanic eruptions, not earthquakes.

• Subduction zones have no effect on the distribution of earthquake epicenters.

How does Plate Tectonic Theory explain the occurrence of volcanic activity along mid-ocean ridges?

• Subduction of oceanic plates

• Collision of continental plates

• Seafloor spreading

• Erosion of oceanic crust

Explain the concept of seafloor spreading and its connection to Plate Tectonic Theory.

• Seafloor spreading is the process by which new continental crust is formed and moves away from mid-ocean ridges, supporting the Plate Tectonic Theory.

• Seafloor spreading is the process by which old oceanic crust is destroyed and sinks into the mantle, contradicting the Plate Tectonic Theory.

• Seafloor spreading is the process by which new oceanic crust is formed and moves towards mid-ocean ridges, opposing the Plate Tectonic Theory.

• Seafloor spreading is the process by which new oceanic crust is formed and moves away from mid-ocean ridges, supporting the Plate Tectonic Theory.
