a reason for temperature inversion in the valley​

Answers

Explanation:

Temperature inversion layers, also called thermal inversions or just inversion layers, are areas where the normal decrease in air temperature with increasing altitude is reversed and the air above the ground is warmer than the air below it. Inversion layers can occur anywhere from close to ground level up to thousands of feet into the atmosphere.

Inversion layers are significant to meteorology because they block atmospheric flow which causes the air over an area experiencing an inversion to become stable. This can then result in various types of weather patterns.

More importantly, though, areas with heavy pollution are prone to unhealthy air and an increase in smog when an inversion is present because they trap pollutants at ground level instead of circulating them away.

Causes

Normally, air temperature decreases at a rate of 3.5°F for every 1,000 feet (or roughly 6.4°C for every kilometer) you climb into the atmosphere. When this normal cycle is present, it is considered an unstable air mass, and air constantly flows between the warm and cool areas. The air is better able to mix and spread around pollutants.

During an inversion episode, temperatures increase with increasing altitude. The warm inversion layer then acts as a cap and stops atmospheric mixing. This is why inversion layers are called stable air masses.

Temperature inversions are a result of other weather conditions in an area. They occur most often when a warm, less dense air mass moves over a dense, cold air mass.

This can happen, for example, when the air near the ground rapidly loses its heat on a clear night. The ground becomes cooled quickly while the air above it retains the heat the ground was holding during the day.

Temperature inversions also occur in some coastal areas because upwelling of cold water can decrease surface air temperature and the cold air mass stays under warmer ones.

Topography can also play a role in creating a temperature inversion since it can sometimes cause cold air to flow from mountain peaks down into valleys. This cold air then pushes under the warmer air rising from the valley, creating the inversion.

In addition, inversions can also form in areas with significant snow cover because the snow at ground level is cold and its white color reflects almost all heat coming in. Thus, the air above the snow is often warmer because it holds the reflected energy.

What is one advantage of a direct democracy?
Decision making can be slow since many people's views must be heard.
No one person has all the power, so poor or selfish decisions are less likely to be made
by the governments.
Every citizen has the right to vote on issues.
All groups in a country are represented when decisions are made.

Answers

Answer:

No one person has all the power, so poor or selfish decisions are less likely to be made

by the governments.

Explanation:

Direct democracy, which is also called pure democracy is a democracy in which the decisions are not taken by representatives. All decisions are voted on by the people. When a budget or law needs to be passed, then the idea goes to the people. Large governments rarely make decisions this way.

I believe this is the most logical answer. Tell me if I am wrong, Thanks!

Explanation:

Erosion can be defined as the process in which the top layer of the soil is removed because of the action of the agents like wind, water, chemicals, and others. Possible soil creep no agent is mentioned responsible for the soil creep whether it is because of gravity, water, or wind. Evidence of a past debris indicate that the erosion has occurred and displaced the debris from its place. Rapid river can also become an agent in South America.

View Available Hint(s) Which of the following statements is best supported by the data in the Insolation layer? The slopes of the Himalayas represent an area of uniform insolation. The cloud cover of the ITCZ limits insolation just south of the equator at this time. At this time of year, insolation is generally greater in the Antarctic polar region than the Arctic polar region. The regions of highest and lowest insolation in the contiguous United States are both located in the western part of the country. North Africa receives substantially less insolation than Sub-Saharan Africa

Answers

Answer:

North Africa receives substantially less insolation than Sub-Saharan Africa.

Explanation:

North Africa receives less solar radiation from the sun as compared to Sub-Saharan Africa because north Africa is far from equator whereas the Sub-Saharan Africa is located near and on the equator zone. Those regions who are on the equator experience direct solar radiation of sun that leads to higher insolation as compared to areas which is far away from equator receives lower insolation so that's why North Africa have low insolation as compared to Sub-Saharan Africa.
