Year 8 Week 6 Homework Term 1

Which scientific theory explains the movement of Earth's lithospheric plates and the geological phenomena associated with their interactions?

• Fossilization

• Plate Tectonics

• Continental Drift

At a divergent plate boundary, what geological feature is commonly formed?

• Trenches

• Volcanic arcs

• Mid-ocean ridges

What type of plate boundary is characterized by plates sliding past each other horizontally, causing earthquakes along transform faults?

• Convergent boundary

• Divergent boundary

• Transform boundary

What type of plate boundary is associated with the collision and subduction of tectonic plates, leading to the formation of deep ocean trenches and volcanic arcs?

• Divergent boundary

• Convergent boundary

• Transform boundary

What force is primarily responsible for the movement of tectonic plates at divergent boundaries?

• Compression

• Shear stress

• Tension

Which tectonic plate boundary is characterized by plates moving apart from each other, leading to the creation of new oceanic crust?

• Convergent boundary

• Divergent boundary

• Transform boundary

What natural events can trigger a tsunami?

• Earthquakes

• Hurricanes

• Tornadoes

What is the primary factor that causes tsunamis to become dangerous when approaching coastlines?

• Strong winds

• Rapid ocean currents

• Shoaling effect (increase in wave height near shore)

What proactive strategy can help lessen the impact of tsunamis on coastal communities?

• Building tall structures near the coastline

• Implementing early warning systems

• Ignoring evacuation orders
