Question

Answer the questions based on the information given.

Answer 1

Answer:

A. 5 × $10^{-3}$ m/year

B. 5 × $10^{3}$ m

C. A river basin

Explanation:

A. The rate of motion of Amur plate can be determined by,

Rate of motion (speed) = $\frac{distance covered}{time}$

given that; distance moved = 125, 000 meters and time = 25 million years (25 ×$10^{6}$ years)

Rate of motion (speed) = $\frac{125 000}{25 000 000}$

                                      = 5 × $10^{-3}$ m/year

The rate of motion of Amur plate is 5 × $10^{-3}$ m/year.

B. After 1 million years, the plate would be at;

                5 × $10^{-3}$ m/year × 1 × $10^{6}$ years

            = 5 × $10^{3}$ m

After 1 million years, the plate would be at 5 000 m.

C. The geological feature that could form between the Amur and Eurasian is a river basin.
