How do mountains affect the climate of a region?

(giving brainlist)

Answers

On the windward sides of mountain ranges, they raise precipitation. When they move toward land, they cause cold, moist air from the oceans to rise. On the leeward sides of mountain ranges, they reduce precipitation totals.

(Hope this helps!!!) Can I pls have a brainliest??

Answer:

As context, there are two sides of a mountain range:

A) The windward side

B) The leeward side

As mountains are tall, they block clouds which are in the troposphere. All the moisture thus falls onto the windward side, while almost none of the moisture from the rain gets to the leeward side.

In a nutshell, mountain ranges create barriers for precipitation which blocks off moisture to the leeward side, creating deserts.

This is why you see mountain ranges near deserts.

During the daytime, the land warms up faster than water causing the air above the land to be less dense and rise into the atmosphere. What will this cause?

Answers

Answer:

The faster warming of the earth than water that causes the air above the land to be less dense and rise into the atmosphere will result in Sea breezes

Explanation:

Land and Sea breezes are phenomena which occur through the heat transfer process of convection.

Sea breezes occur mostly during the hot summer afternoons because of the unequal heating of land and water. During the day, both the land and sea receives equal amounts of heat from the sun, but,  the land surface heats up faster than the water surface. Therefore, the air above the land becomes heated up more and is warmer than the air above the ocean. The air above the land to become less dense and as result, the warm air rises into the atmosphere.  However, at the ocean surface, the air above is is colder and hence, denser than the warm air over the land surface. Thus, the air pressure at the ocean surface is greater than at the earth's surface. As the warm air over the land is rising, a convection current is set up and the cooler air over the ocean flows with the aid of the wind and replaces the warm air from earth's surface. This is known as sea breeze.

condensation of water vapor during the day, and evaporation of water during the night
3.
convection resulting from temperature and pressure differences above land and water
4.
greater radiation from the warmer ocean during the day and from the warmer land at night
Submit Answer

Answers

Answer:

3. convection resulting from temperature and pressure differences above land and water

Explanation:

Due to the the difference between the ability of land and to water to absorb and radiate heat energy, the land gets heated up by the sun more quickly than water during the hot afternoons. As a result, the air above the land surface gets heated up more quickly than that above water. Warm air being less dense than cold air will rise above to atmosphere creating a low pressure area on land. On the other hand, air above water is not heated up as quickly, thus the dense cooler air over water will rush in and replace the warm air that has risen above the land surface.

At night, the land cools off more easily than water, hence the air above the land surface is cooler. On the other, water does not lose heat as quickly as the land, hence the air above the water surface is warmer than that over land. Warm air over the water surface will rise above, while colder air from land will replace it.

There are 450 calories in 100 g of trail mix. If you burn 30 calories in 10 minutes of walking, how much trail mix should you eat to replenish the energy you spend walking for 2 hours?

Answers

Answer:

to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

Explanation:

Firstly, let us calculate the number of calories burnt in 2 hours

in 10 minutes; 30 calories are burnt

∴ in 1 minute 30/10  calories are burnt = 3 calories are burnt

2 hours = 120 minute

∴ in 120 minutes 3 × 120 = 360 calories are burnt.

Next, let us calculate the amount of trail mix that contains 360 calories

100g of trail mix = 450 calories

450 calories = 100 g

1 calory = 100/450

∴ 360 calories = 360 × (100/450)

=  360 × 0.222 = 80g

∴ to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

Instead of dining out on a meal of seafood sausage, crusty bread, and cheese, you walk over to a well-known fast-food restaurant for a hamburger. For many tourists, the sight of familiar logos and menus from home are in enough locations that they might even forget they are in a different country!When people speak of globalization, they are referring to the movement and integration of people and goods from different countries. In an ideal world, globalization is good for sharing ideas, building economies, and helping countries discuss ways to work together. Globalization has been held up as the solution to many world problemsfrom overcoming poverty to better treatment of workers.There are other areas in which globalization is easy to see, such as in music, television, and movies. Social apps used for communication are also in use around the world. This brings another level of influence from the country creating them.However, there is one disadvantage that accompanies this globalization. Quite simply, globalization kills cultures. And when cultures become lost, so can the national identities of a group and a people.Why?Corporations and large businesses have brands to sell. When one city after the next brings only a handful of these companies into their country, it turns cities into clones of each other. In the race of some countries to take over markets in other countries, the unique aspects of cultural identity get left behind. Those fast-food restaurants and coffee shops are great for business and the economybut at what price?While different languages might distinguish Paris, London, Milan, and Berlin, it is hard to ignore the rapidly increasing sight of American influence. Restaurants, stores, and even theme parks have found their way into various locations in Europe. A person may feel comforted by the sight of a sandwich chain and may even know exactly what item on the menu they want to order. But the restaurants presence in a foreign country is symbolic of something much bigger; the values of a dominating culture have seeped into many other cultures. And because of the promise of financial success in a region that has possibly struggled for profitable business, that culture dismisses their own values and identity for something that appears to be more valuable.What effect does this have on a cultures ability to remain important, especially in the lives of young people? Advertising, created by the influence of western culture, now heavily influences them. Much of what is put forth as desirable is in an effort to sell something and make money. Unfortunately, what is popular at the time will change very quickly. With slick advertising that is seen repeatedly, people are persuaded to part with their hard-earned money in a never-ending quest to buy products that they are convinced will improve their lives.Another area that shows the impact of globalization is fashion. T-shirts and jeans are normal for casual wear. Business suits are worn for professional purposes. Traditional clothing from various countries has not disappeared altogether, as it is worn generally for special occasions such as festivals or performances. But there remains the risk of these celebrations becoming less important as the cultures values keep changing.Gone is the traditional clothing created generations ago. Gone is the music one may have heard as a child. Gone is the heritage of a people in favor of buying the latest digital technology or clothing. Stories, history, and connection have been sacrificed.How will the young people know who they are without the rich and meaningful traditions of their ancestors? What happens to cultures not rooted in financial success?Here is a scenario: Think of a grandmother in the United States out with her daughter, son-in-law, and grandchild. Maybe they are eating at a fast-food restaurantsomething which the grandmother has never done except in the last 20 years. The television is blaring overhead with graphic music videos and commercials selling sports cars. Her children are staring at their mobile phones. Her grandson is playing with a computer tablet. The bright lights of the computers and thumping beat of music drown out the possibility of having a meaningful conversation.How does this grandmother communicate the importance of their familys culture and traditions to younger family members? How does she convey the way her grandmother sang while weaving intricate blankets, or how her grandfather explained the meaning of her name?Sadly, with increasing difficulty.
