Balanced Biosphere - Task 1 - Evidence of Continental Drift

Front

What is the Theory of Continental Drift?

Back

The theory states that the continents were once joined in a super-continent and have moved over time based on geological evidence.

Front

Who proposed the Theory of Continental Drift?

Back

Alfred Wegener, a German scientist, proposed the theory 100 years ago.

Front

What evidence supports the idea that Africa was once in a cold climate?

Back

Glacier scars found in Africa indicate that it was once located in an area with a very cold climate.

Front

What can we infer when the same reptile fossil is found in two different locations?

Back

We can infer that the habitats used to be near each other.

Front

What similarities are found in mountain ranges on both sides of the Atlantic Ocean?

Back

They have the same rock types, structures, and ages.

Front

What is a super-continent?

Back

A super-continent is a large landmass that contains multiple continents, which were once joined together.

Front

What role do lithospheric plates play in continental drift?

Back

Lithospheric plates are sections of the Earth's crust that move due to convection currents, causing continents to drift.

Front

What is sea floor spreading?

Back

Sea floor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and pushes older crust away.

Front

What is the significance of fossil evidence in supporting continental drift?

Back

Fossil evidence shows that similar species existed on continents that are now separated, suggesting they were once connected.

Front

How do coal seams provide evidence for continental drift?

Back

Coal seams found in different continents indicate that those areas once had similar climates suitable for coal formation.
