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 most unreliable variable in diagnosing the property
minerals such as quartz is their color as it is not consistent with the use of
such external factors. The color could change, that is why it is considered to
be unreliable in diagnosing some of the minerals.
Answer: Chinese Muslim traders from the eastern coast of China arrived at the coastal towns of Indonesia and Malaysia in the early 15th century. They were led by the mariner Zheng He, who commanded several expeditions to southeastern Asia between 1405 and 1430.
Explanation:
The three main particles of an atom are: electron, proton, and neutron.
This table shows the differences on the three properties: location, charge, and mass, for the three particles:
particle location charge (C) mass (g)
electron space around the nucleus - 1.6 * 10^ -19 9.11 * 10^ -28
proton nucleus + 1.6 * 10^ -19 1.673 * 10 ^ - 24
neutron nucleus 0 1.675 * 10 ^ 24
It is important to drive some conclusions that permit you to have a better picture ot these particles and their differences:
1) electrons are in the space around the nucleus in regions called orbitals. Those are not orbits, because the electrons are not orbiting the nucleous.
2) Both protons and neutrons are inside the nucleus of the atom.
3) Electrons and protons have opposite charges of the same magnitude. The number of protons and electrons in an atom are equal, that is why they are neutral. The neutrons, which are inside the nucleus, with the protons, does not have charge.
4) The mass of the protons and the neutrons are almost equal.The difference does not count for the usual calculations.
5) The mass of one electron is 1 / 1840 times the mass of one proton. A very low quantity.
6) Electron is a fundamental particle (it is not formed by other particles).
7) Protons and neutrons are not fundamental particles. They are formed by quarks.
