Explanation:
The fossil record essentially keeps track of the abundance and appearance of various fossils during different time periods. As time goes on, the fossils change. Using the fossil record, we can compare and contrast the fossils to develop theories about changing life forms and their connection to time.
Hope this helped :)

Explanation:
A sloping line on a speed-time graph represents an acceleration.
To calculate acceleration from a speed-time graph, you divide the change in velocity by the time taken for the change.
