The polar air masses are air masses that form on the high latitudes, in the polar regions. The tropical air masses are air masses that form on the low latitudes, around the equator.
The polar air masses are cold air masses. They are also dry, very dense, and have much higher air pressure. The tropical air masses are warm air masses. Depending have they formed over land or over sea, they can be either dry or moist, and they have low air pressure as they are much less dense.
A typical polar air mass brings in cold and dry weather, while the tropical air mass brings in warm weather, with either lot of precipitation, or being very dry.
The polar air masses are moving from the high latitudes toward the lower latitudes, while the tropical air masses are moving from the lower latitudes toward the higher latitudes.
Is a U-valley formed by movement in glaciers. A glacier or U-shaped valley has a wide flat floor and steep sides.
Glaciers are a thick mass of moving ice. V-shaped valleys become U-shaped valleys as glaciers move through them. First it is a typical river valley and then water flows into the cracks, which over time cuts a deeper V-shape. Glaciers then fill the valley, widen it and stretch the canal, which when the glacier melts leaves a U-shaped valley. Gravity causes the glacier to slide down. Then it pulls rocks, sand and gravel, ie sediment
. These wear down into the rock and form a U-valley. The differences between a V-valley and a U-valley are that a glacier works downwards and outwards while the V-valley then works its way down the glacier. and deepen the valley and change it to a U-shape.
u-shaped valley was formed by ice formation. U-shaped valleys are mostly found near the rocky mountain.
Glaciers pass through jagged mountain valleys making them smooth and u-shaped after the ice retreats.
The ice scrapes the sides and bottom
valleys are low land areas between hills or mountains. they usually have rivers that run through the middle
When a glacier pushes itself forward in a mountain landscape, the ice grinds not only on the surface but also on the sides of the valley and in this way characteristic U-valleys are formed
the valley is formed by erosion, or gradual wear of elements, such as water or wind. valleys can also be formed by movements in the earth's crust or gracias. the graciers drop depressions into the earth's surface
valleys are helpful to people because they are usually close to the river. the flowing stream provides access to food and potable water. they also give people exotic plants and animals to eat or harvest
In what type of landscape can you most often find this landform?
You can find U-dal in mountain areas everywhere in, for example, Sweden, Himalayas
The correct answer to this open question is the following.
The way in that the local governments established by the English colonists reflected major political ideas and traditions in history was the following.
English colonists based their ideas on the government in the concepts of the representative government and limited government. The English people had important documents that influenced the way they established their colonies in America, such as the Magna Carta that was a very representative document of British Politics and law, as well as the English Bill of Rights that later influenced the American Bill of Rights.
