Answer: b) earthquake activity

Options:

a) earth's density

b) earthquake activity

c) volcanic activity

d) atmospheric composition

Explanation:

Earthquake activity : Seismic waves are responsible for the earth trembling during earthquakes. An earthquake occurs as seismic waves travel through the interior of Earth’s surface. A seismograph measures the characteristics of these waves such as how fast they travel as well as their strength.

By studying these attributes in different places, scientists come to understand the makeup of earth’s internal structure. The type of seismic waves most important to this study are body waves which travel through the earth’s interior .

a_sh-v [17]

Answer:

Explanation:Do you live in a city, or in a small town? Or do

you live on a farm or a ranch? Has your family

lived there a long time or a short time? How does

living where you do affect the way you live? For

example, do you need special clothes in the winter? Is your favorite food grown nearby, or is it

brought in from far away?

All these questions have to do with geography.

Geography is the study of our home—the earth—

and how our lives are affected by it. Almost every

detail of our lives is affected by geography. The

clothes we wear, the food we eat, the things we do

for fun, and the kinds of homes in which we live

are all connected to geography.
