Explanation:
An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction.
There are many different types of earthquakes: tectonic, volcanic, and explosion. The type of earthquake depends on the region where it occurs and the geological make-up of that region. The most common are tectonic earthquakes.
The National Earthquake Information Center (NEIC) locates an average of 50 earthquakes every day, or about 20,000 a year.

I'm actually just guessing
Answer:
yeah.people live in everywhere .even in a moon and mars.
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.
