Answer:
3.29ft/mi
Explanation:
The gradient of a river is the slope through which a river flows. It measures the vertical drop in elevation of river to the horizontal distance.
Mathematically;
River gradient =
Elevation = 1229ft
Horizontal distance = 373miles
River gradient = = 3.29ft/mi
Answer:
High clouds are anywhere from 5,000m-13,000m high. Some examples of these kinds of clouds are cirrus and cirrocumulus. Contrails are also included in this altitude.
Middle clouds are located anywhere from 2,000m-7,000m high. Examples of these clouds are altocumulus and altostratus.
Low clouds are located from the surface up to 2,000m. Examples of these clouds are cumulus and cumulonimbus.

The answer is A
Explanation:
Seafloor spreading causes continental plates such as the North American Plate and the Eurasian plate to move apart in the mid-Atlantic ridge. However, the movement of the plate can cause the plates to move towards others. Eventually, when the continental plates move together they form supercontinents. The convection currents in the mantle are the driving force under the tectonic plates.
