Geological Processes and Plate Tectonics

The video tutorial explores the dynamic processes at plate margins, including seafloor spreading and subduction, which lead to geological phenomena like the formation of the Himalayas. It discusses the role of volcanic eruptions and earthquakes in shaping landforms, distinguishing between intrusive and extrusive types. The Pacific Ring of Fire is highlighted as a significant zone of volcanic activity.

What is formed as a result of seafloor spreading along mid-ocean ridges?

• Deep ocean trenches

• Mountain ranges

• Volcanic islands

• New oceanic crust

What happens when an incoming tectonic plate meets a stable plate?

• The stable plate moves over the incoming plate

• The incoming plate slides alongside the stable plate

• Both plates stop moving

• The incoming plate dips under the stable plate

Which mountain range was formed by the Indian plate pushing into the Eurasian plate?

• Andes

• Rockies

• Himalayas

• Alps

What are the two main geological activities that occur at plate boundaries?

• Floods and droughts

• Volcanic eruptions and earthquakes

• Hurricanes and tornadoes

• Tsunamis and landslides

What are the two types of changes in the lithosphere discussed in the video?

• Erosion and deposition

• Slow movements and sudden eruptions

• Glaciation and melting

• Weathering and sedimentation

What is the term for the molten rock that erupts from a volcano?

• Granite

• Basalt

• Sandstone

• Lava

What type of landform is created when lava cools and solidifies on the Earth's surface?

• Metamorphic landform

• Extrusive landform

• Intrusive landform

• Sedimentary landform

What is the Pacific Ring of Fire known for?

• Having the highest mountain peaks

• Having the most diverse wildlife

• Being a major earthquake zone

• Being the largest desert

What happens to magma that does not reach the Earth's surface?

• It creates intrusive landforms

• It forms extrusive landforms

• It turns into sedimentary rock

• It evaporates

What percentage of land is controlled by volcanoes in the Pacific Ring of Fire?

• One-third

• One-half

• Two-thirds

• One-fourth
