3 Based on the thin layer of sediment on his flooded farm,
James Hutton concluded that strata:
A Are made of large rocks
B
Settle in vertical layers
C
Are formed by catastrophes like floods and earthquakes
D
Take many thousands of years to form

D. Take many thousands of years to form

Explanation:

James Hutton discovered thin layers of sediments on his flooded farm and he concluded that strata was part of the earth surface in the past and thus takes many thousands of years to form.

This led to the principle of uniformitarianism which states that the geologic processes now are the same with the ones in the past.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
