Answer 1

A 'fossil' is evidence of ancient life, and the 'fossil record' documents life on Earth. 'Plate tectonics' cause surface changes, while an 'ice age' is a period of catastrophic cooling. 'Pangaea' was a supercontinent evidenced by similar fossils on different continents.

Step-by-step explanation:

The remains, impression, track, or other evidence of a once-living ancient organism is called a fossil. The history of life on Earth, as documented by fossils, is known as the fossil record. It will never be complete because most organisms decompose too quickly to be preserved. The slow movement of Earth's plates due to plate tectonics causes gradual changes to the surface. Some events are more catastrophic, like the cooling temperatures and the covering of Earth in glaciers that occurs during a(n) ice age. Similar fossils and rocks now found on separate continents suggest they used to be one massive supercontinent, known as Pangaea.
