Geography

7 0

Answer:

In simple words, there existed no living on Earth for the first few million years since the environment was unsuitable for life. The original atmosphere of the Earth had a lot of water vapor but practically little oxygen. Volcanic activity blasted substances into the atmosphere such as nitrogen, carbon dioxide, hydrogen, and water vapor, but no pure oxygenation.

The Rate of movement of the Pacific Plate will be 37.87cm per year.

Underneath the Pacific Ocean is an oceanic tectonic plate known as the Pacific Plate. It is the largest tectonic plate at 103 million km2. The Farallon, Phoenix, and Izanagi Plate triple junction are where the plate initially formed 190 million years ago.

From the information given, the following can be deduced:

Distance = 500 km = 50000000cm

Time = 1.32 million years = 1320000 years.

Therefore, the rate of plate movement will be (i.e. speed) :

(speed) = Distance / Time

(speed) =  50000000 / 1320000.

(speed) = 37.87 cm/yr
