• Wind currents in the atmosphere

• Earth's magnetic field

• Ocean tides

Multiple Select

Which of the following are features formed at divergent boundaries?

• Mid-Atlantic Ridge

• Rift valleys

• Deep ocean trenches

• Mountain ranges

Multiple Choice

Which of the following provide evidence for plate movement?

• Matching fossils on different continents

• Similar rock formations across oceans

• Puzzle-like fit of continents

• All of the above

Multiple Choice

Which of the following is NOT a result of plate tectonics?

• Formation of mountain ranges

• Creation of ocean basins

• Development of islands

• Formation of deserts

Multiple Choice

What is the role of the asthenosphere in the movement of tectonic plates?

• It provides a rigid base for the plates to rest on

• It acts as a layer of hot, partially melted rock that allows plates to float and move

• It is the outermost solid layer of the Earth

• It is responsible for the formation of mountains
