Explain the difference between a Long Profile and a Cross Profile of a River.

Geography
1 answer:
dimulka [17.4K]3 years ago

Answer:

The average flow velocity of a river increases along its long profile. This makes sense; along the profile, more potential energy is converted to kinetic energy, increasing the velocity. This is only the average velocity however; a cross-section of a river shows that the velocity varies from one side to the other.

A scientist observes that over several decades, fence posts placed in soil on a slope became tilted. Have erosion, deposition or
Oksana_A [137]

Answer:

Erosion

Explanation:

At first the fence posts were straight up, but over time that became tilted. The reason fro this is erosion. The erosion managed to remove part of the ground in whist he fence posts have been placed, thus their basis has been weakened, and they have tilted. If the process continues they will soon fall on the ground. Deposition has occurred for sure somewhere, but from this information it is not clear where. There has not been deposition on one side and erosion on other as the fence posts would have been standing straight if that happened. The deposition always occurs as a result of the erosion, but the material can be deposited anywhere from few cm away to several thousands of km away., depending on the transferring medium.

Cooling because of air expansion is called ________.
enot [183]
The answer is - adiabatic lapse rate.

Adiabatic lapse rate refers to the rate at which the air expansion cools. For the dry air it has the value of 9.8 degrees per kilometer. When the air that is saturated starts rising and cools, the process of condensation of water vapor begins, releasing latent heat in the process.

In the Middle East, you can expect mainly earthquakes to happen. Earthquakes also result in other natural disasters such as mudslides and floods. To prepare for earthquakes, you can pratice what to do during an actual earthquake such as if you're a farmer and outside, you would want to get to an open area to avoid powerlines, trees, or anything that could come down. To also prepare for or prevent a mudslide, plant and water diversion are good methods to stay safe. You can also make sure you plant appropriately on hills. For floods, you can always ask others about relocation routes and centres. On top of that, if possible, you can prepare a household flood plan.
