The shapes of the continents tell us that they were once connected as a single landmass called Pangaea over 200 million years ago. The movement of tectonic plates caused the continents to drift apart to their current positions, creating the geography we see today. This process is known as plate tectonics.

What do the shapes of the continents now tell us about the past?
The shapes of the continents provide evidence of past tectonic activity, such as the splitting of continents through plate tectonics. For example, the fit of the continents' coastlines, like the matching shapes of South America and Africa, suggests they were once joined. This helps us understand the movement of Earth's plates over millions of years.
What do the shapes of the continents now tell us about their past?
The shapes of the continents suggest that they were once connected as a single landmass known as Pangaea, which later drifted apart due to the movement of tectonic plates. The matching coastlines and geological evidence support the theory of continental drift and plate tectonics.
What do the shape of the continents now tell us about their past?
The current shape and position of continents provide evidence for the theory of plate tectonics, which suggests that continents were once part of a supercontinent called Pangaea that has since drifted apart. This movement helps explain the similarities between the geology and fossils of now widely separated continents, as well as the presence of matching coastlines and mountain ranges.
What is the idea that continents now separated by an ocean were once attached?
This concept is known as continental drift, which suggests that the Earth's continents were once part of a single landmass called Pangaea and have since drifted apart over millions of years due to the movement of tectonic plates. This theory is supported by geological evidence such as similar rock formations, fossils, and the matching shapes of coastlines on different continents.
Why don't the present shapes of the continents fit perfectly into a super continent?
As the continents moved further apart, natural erosion of the Coastlines removed and added to the basic shape over billions of years. Much of the evidence relates to the similarities of plants and animals found on now separate continents. Geological evidence points to Antarctica was once further north and had a tropical climate!

Why don't the shapes of the continents now fit together exactly?
The shapes of continents do not fit together exactly because they have been moving and shifting over millions of years due to plate tectonics. This movement has caused the continents to break apart and drift apart from each other, resulting in their current shapes. Additionally, erosion and other geological processes have also altered the original shapes of the continents.

Can you describe 3 clues that support the idea of continental drift?
Fit of the continents: The way the continents' coastlines fit together like puzzle pieces suggests they were once connected. Matching rock formations: Similar rock formations, mountain ranges, and geological features on different continents provide evidence of a shared history. Fossil evidence: The presence of the same fossils on continents that are now separated by vast oceans indicates that they were once part of the same landmass.

Which continents of today were a part of Gondwanaland?
The continents of South America, Africa, Antarctica, Australia, the Indian subcontinent, and the Arabian Peninsula were all part of Gondwanaland. Today, these landmasses have drifted apart and now form separate continents.
Why do five continents take part in the Olympic games when there are now seven?
The continents of North America and South America are considered as one (called the Americas) and Antarctica is not included because there are no indigenous people from there.
