If willing to, PLEASE help me with this I’m not sure how to answer . Thank you . (By the way I’m not sure what to put for the subject

1.) How does fossil data support the fact that the Earth’s surface has changed in the past and therefore will change again in the future?

2.) What do scientists know about mountain ranges and continental shelves that could be used as evidence to support how the Earth’s surface has changed in the past and therefore will change again in the future?
