Answer:
North Africa receives substantially less insolation than Sub-Saharan Africa.
Explanation:
North Africa receives less solar radiation from the sun as compared to Sub-Saharan Africa because north Africa is far from equator whereas the Sub-Saharan Africa is located near and on the equator zone. Those regions who are on the equator experience direct solar radiation of sun that leads to higher insolation as compared to areas which is far away from equator receives lower insolation so that's why North Africa have low insolation as compared to Sub-Saharan Africa.
The resulting erosion at the base of a waterfall can be very dramatic, and cause the waterfall to "recede." The area behind the waterfall is worn away, creating a hollow, cave-like structure called a "rock shelter." Eventually, the rocky ledge (called the outcropping) may tumble down, sending boulders into the stream

Answer:
c. fossils
Explanation:
Fossils are the remains of dead and decayed organisms that are preserved in rocks. Fossils can be preserved using their hard parts, or the products of their activities can remain still for several years.
Fossil are used for relative age dating of rocks. According to the principle of fossil and fauna succession, it is scientifically correct to correlate areas with the same fossil record because fossils succeed on another in a definite order. All rocks that exists in that time period will contain the organisms that lived during that period in time.
