Which plate is the North American plate moving away from?

The correct answer is: The trench is formed by a subduction zone which has also created volcanic islands.

As all the other trenches on the plate boundaries of the Pacific plate, the Aleutian Trench, on the boundary between the Pacific and the North American plate, has also come to be because of the subduction zone appearing between the two plates.

The lower and heavier Pacific plate is subducting bellow the North American plate, and that results into large deep spaces opening up between the two plates, thus the emergence of the trenches. Also, because the magma from bellow the crust has easy access to the surface, it comes upwards and creates multiple islands with the volcanic activity that it produces.

The correct answer is - 1,180 km.

North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.

To get to the result we only need to multiply the number of years with the annual movement

2 x 200,000 = 400,000

Than divide the result with 100,000, as that is how much cm are in one km

400,000 / 100,000 = 4

And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.

The Answer is D

Explanation:

The time, t it will take LA and San Francisco to be next to each other is 8,245,614.04 years which is over 8 million years

Step-by-step explanation:

The given parameters are;

The speed with which the pacific plate moved northward relative to the North American plate = 5.7 cm/year = 5.7 × 10⁻⁵ km/year

The distance between current LA and San Francisco = 470 km

From the formula for speed, s, we have

Speed = Distance/Time

Therefore, Time, t = Distance/Speed

The time, t it will take LA and San Francisco to be next to each other is given as follows;

t = (Distance between LA and San Francisco)/(The speed with which the pacific plate)

t = (470 km)/(5.7 cm/year) = 470/(5.7 × 10⁽⁻⁵⁾) = 8245614.04 years

Therefore, the time, t it will take LA and San Francisco to be next to each other is 8245614.04 years.

The answer is; Divergent boundary zone; volcanic activity; fissure zones

The mid-Atlantic ridge is a divergent boundary. Such a boundary, that majorly occurs in ocean beds, is exhibited by signs of ocean-floor spreading. As the two plates move away from each other, the magma from the mantle rises to fill the void. Mountain ranges form along the boundary due to the numerous fissures between the two plates.
