Answer:
A plateau is a raised, flat-surfaced area bound on one or more sides by cliffs or steep slopes.
Explanation:
Earth is a planet that has all sorts of different types of landforms. Some are enormous and occupy thousands of square km while some are very small and barely noticeable. One interesting landform that varries from medium to large size is the plateau.
The plateaus are flat or relatively flat areas that are on higher elevation. They differ in size, but also in elevation, and a plateau can be anywhere from 600 meters above sea level (like Pelagonija)to the highest ones that are above 4000 meters of elevation (like the Tibetan plateau). In some cases the plateaus are the highest landforms int heir surroundings and they bordered cliffs and steep slopes, in some cases it is a mixture of higher mountains on one side and cliffs and steep slopes on the other, and in some cases, they are fully surrounded by mountains, which is why people tend to confuse them with valleys if they are not very high.

A jet stream is a narrow variable band of very strong predominantly westerly air currents encircling the globe several miles above the earth.
