What is the Theory of Plate Tectonics?

Back

The Theory of Plate Tectonics explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere beneath them.

What evidence supports the Theory of Plate Tectonics?

Back

Evidence includes the fit of continental coastlines, fossil distribution across continents, and geological similarities between continents.

What is a land bridge in the context of plate tectonics?

Back

A land bridge is a land connection between two larger landmasses that allows species to migrate, which is not considered evidence for the Theory of Plate Tectonics.

What are the characteristics of planets in our Solar System?

Back

All planets are large celestial bodies that orbit the Sun, have sufficient mass for their self-gravity to overcome rigid body forces, and have cleared their orbital paths.

Front

What keeps planets in orbit around the Sun?

Back

Planets are kept in orbit by the gravitational pull of the Sun balanced with their inertia.

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust.

What is the significance of the term 'divide' in relation to divergent boundaries?

Back

'Divide' refers to the action of tectonic plates moving apart, leading to the creation of new geological features such as mid-ocean ridges.

What is Continental Drift?

Back

Continental Drift is the hypothesis proposed by Alfred Wegener that all continents were once part of a single landmass that broke apart and drifted to their current locations.

What evidence did Wegener use to support his hypothesis of Continental Drift?

Back

Wegener used evidence such as the fit of continental coastlines, fossil evidence, and geological similarities across continents.

What is the role of inertia in planetary motion?

Back

Inertia is the tendency of an object to resist changes in its state of motion, which helps planets maintain their orbits around the Sun.
