Question

Answer the questions based on the information given.
The Amur plate, a small plate, has moved away from the Eurasian plate. It has moved 125,000 meters in 25 million
years. It is moving eastward.
mm
What is the rate of motion of the Amur plate? Express your answer in Year
Where would the plate be after 1 million years? Express your answer in m
What geologic feature will form between the Amur and Eurasian plates?

Answer 1

to part A the answer is :5 mm/year  

to part B the answer is: 5,000 meters east

and finally for part c the answer is new ocean floor

Hope I helped :D

Answer 2

The rate of motion of the Amur plate is 0.005 meters (m) per year; whereas the plate will move 5,000 meters (m) east after 1 million years. Moreover, a NEW OCEAN FLOOR will form between the Amur and Eurasian plates.

• The rate of motion (R) can be calculated as:

           R = 125,000 meters (m) /25,000,000 years = 0.005 m/year

• The movement of the plate can be estimated as:

            1 year _____________ 0.005 m east

            1,000,000 years ____  X = 1,000,000 x 0.005  >>

            X = 5,000 meters east

• It is well known that new seafloors are continually formed in regions where oceanic plates move apart during seafloor spreading. In this case, a new ocean floor will form between the Amur and Eurasian plates.

In conclusion, the rate of motion of the Amur plate is 0.005 meters (m) per year; whereas the plate will move 5,000 meters (m) east after 1 million years. Moreover, a NEW OCEAN FLOOR will form between the Amur and Eurasian plates.
