Answer:
<u>Wegener gave many evidence to the theory of plate tectonics another piece of evidence was the finding of fossils of reptiles in oceans and glossiperious fauna and the similarity of glaciers in all continents</u>
Explanation:
- Alfred Wegener is supposed to believe that the supercontinent named Pangaea consisting of northern continents and the southern continent i.e Gondwanaland consisting of southern continents were once the same.
- Thus he gave evidence in the shape of puzzle-like fit of the continents as similarity of rocks found in the continent's of Africa and South America, as they were one earlier.
- Further, he gave the supporting pieces of evidence as the glacier landmasses distributed were the same part earlier drifted away from the larger continent of Greenland.
- The supporting evidence the put forth was the polar wandering forces that he called the flight from poles and drift under the impact of moons gravity and another evidence was the thin sheets or plate moved away due to the wind.
The unconformity that is found in a geological cross section indicates that in this area erosion happened.
Erosion is a natural process in which the surface of the Earth (<span><span>soil, rock, or dissolved material</span>) gets worn down.
The cause for erosion can be wind, water, glacier ice or other natural element.

Explanation:
Surface area is 54cm²
, volume is 27cm³
and surface area-to-volume ratio is 2
Explanation:
If s is the side of a cube, then its surface area is 6s²
and its volume is s³
Hence, if the sides of a cube are 3 inches long
its surface area is
6×3²
=6×9
=54cm²
,
its volume is 3³=27cm³
and surface area-to-volume ratio is
54/27=2
