Answer 1

The image of the U-shaped glacial valley in Yosemite Valley, California provides evidence of climate change over geologic time.

Step-by-step explanation:

The image of the U-shaped glacial valley in Yosemite Valley, California provides evidence of climate change over geologic time. The topography of the valley, with its U-shape, indicates that it was formed by glacial erosion. This suggests that glaciers were present in Yosemite Valley during a colder climate in the past. However, the presence of receding glaciers and the melting of ice in the present indicate that the climate has warmed over time.
