The most active volcanoes are located in South America and the bottom of North America
The features that result as a form of a glacier carving out rock and forms into the landscape over which it slides are called cirques. When a glacier moves it erodes the surface of the earth beneath it. In this process of erosion large boulders and very small pebbles all get caught up in the path of the glacier and move along with it. This moment causes deep depressions into the earth, changing the landscape. The deposition of rocks and silt from a melting glacier also changes the form of the land over which the glacier moves.

Answer:
James Hutton
Explanation:
James Hutton was the geologist who brought this concept of 'Uniformitarianism'. This law describes that all the geological processes that occur now must have taken place in the geological past, with varying intensities, and these processes are responsible for the configuration of the landscape and formation of various surface features on earth.
This was an important discovery that led to a better understanding of the geological processes and how they act on the earth's surface and in its interior.
Given:
Similar triangles ABC and PQR with AB = 4 and PQ = 7.
To find:
The scale factor, ratio of perimeters, and ratio of areas.
Solution:
In similar figures the scale factor is the ratio of side or image and corresponding side of original figure.
In similar triangles ABC and PQR, the scale factor is
The scale factor of triangle ABC to triangle PQR is 
.
The ratio of the perimeters of similar triangles is equal to the ratio of their corresponding sides.
The ratio of the perimeters is 4:7.
The ratio of the areas of similar triangles is equal to the ratio of squares of their corresponding sides.
Therefore, the ratio of the areas is 16:49.
