Plate Tectonics - Brain POp

Who is the scientist credited with proposing the theory of the supercontinent called Pangaea?

• Harry Hess

• Alfred Wegener

• Charles Darwin

• Marie Curie

What evidence did Alfred Wegener use to support his theory of continental drift?

• Similar rock layers and fossils found on continents separated by oceans

• The discovery of the Mid-Atlantic Ridge

• Direct observation of continents moving

• Measurements of the Earth's core temperature

What is the process called where new seafloor is formed at mid-ocean ridges and spreads outward?

• Continental drift

• Subduction

• Seafloor spreading

• Convection currents

What is the innermost layer of the Earth, which is scorching hot?

• Mantle

• Crust

• Lithosphere

• Core

What do we call the large, rigid pieces that make up the Earth's lithosphere?

• Continents

• Plates

• Landmasses

• Blocks

What is the movement of the Earth's plates, driven by convection currents in the mantle, called?

• Continental shift

• Plate tectonics

• Seafloor subduction

• Geological erosion

What are the three main types of plate boundaries?

• Hot, cold, and neutral

• Convergent, divergent, and transform

• Upper, middle, and lower

• Active, passive, and stable

Where do volcanoes commonly form due to plate tectonics?

• Only in the middle of continents

• At divergent boundaries and subduction zones

• Randomly across the ocean floor

• Only where two continental plates collide

What geological feature is formed when two continental plates converge and buckle?

• Oceanic trenches

• Mid-ocean ridges

• Mountain ranges

• Volcanic islands
