3.1 Pangea, Geological Time-Scale & Fossil Record

Front

What is Pangea?

Back

Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all the continents were joined together.

Front

What is continental drift?

Back

Continental drift is the theory that continents move across the Earth's surface over geological time.

Front

What evidence supports the theory of continental drift?

Back

Evidence includes the shape of continents, similar fossils found on separate continents, and glacial features in warm areas.

Front

What type of rock are fossils typically found in?

Back

Fossils are usually found in sedimentary rock.

Front

What era is known as the age of dinosaurs?

Back

The Mesozoic Era is known as the age of dinosaurs.

Front

What are fossils?

Back

Fossils are the preserved remains or traces of ancient organisms.

Front

What is the geological time scale?

Back

The geological time scale is a system of chronological dating that relates geological strata to time.

Front

What is the significance of the fossil record?

Back

The fossil record provides evidence of the history of life on Earth and shows how species have changed over time.

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed by the accumulation of sediments, often containing fossils.

Front

What is the Precambrian Time?

Back

Precambrian Time is the earliest part of Earth's history, covering about 88% of Earth's geological time.
