ASAP PLEASE HELP: What is convection and how does it contribute to making Death Valley so hot?

Answers

Answer 1

Answer:

Death Valley’s crazy heats are caused by a combination of the lack of water, geography, and materials that make up the valley.

The average yearly rainfall in Death Valley is only 2 inches. This is less than many other deserts in the world, averaging around 10 inches of rain annually. This intense lack of water also creates a lack of plants in the area resulting in the expanses of sand in the valley open to constant heating by the sun.

Sea level in Death Valley

Driving into the valley you get to experience the geography of the environment, traveling from 1000 feet to 4000 feet above sea level and down to 100 feet below sea level. These mountain ranges you drive over top 4000 feet and surround the lowest point in the United States of 282 feet below sea level. This creates an interesting phenomenon of trapping the hot air within the valley.

Sand and rocks make up the valley floor which radiate a large amount of heat. However, because of the geography, this hot air cannot escape. Instead, the hot air rises along the valley walls, cools slightly and then falls back to the valley floor to be heated even more by the hot sand and low elevation air pressure. This concept of movement by heating and cooling is called convection and exists in many other life circumstances like the boiling of water or in a kitchen oven. Despite the movement of air and possibility of high winds, the winds do not do much to cool down the hikers in the valley because the wind is still very hot.

The heat can be so extreme that signs in the park advise turning off the air conditioning in certain areas to avoid overheating of cars, making the experience an even toastier one. Additionally, hiking is recommended only before 10am and with lots of water.

Despite the heat it is worth braving the heat to experience the truly unique views of Death Valley. This unique environment allows for rock formations, salt flats and expanses unlike anything else in the United States.

A beverage store charges a base price of x dollars for one keg of root beer. A sales tax of a certain percentage is applied to the base price, and an untaxed deposit for the keg is added. If the total amount, in dollars, paid at the time of purchase for one keg is given by the expression 1.07x+17, then what is the sales tax, expressed as a percentage of the base price? (Fully Explained)

Answers

Answer:

7% is the sales tax.

Explanation:

So, our base price is x dollars:

x = base price

Now, we are given the expression 1.07x + 17

This expression can be rewritten as:

(1.00 + 0.07)x + 17

Also seen as:

(100% + 7%)x + 17

We know that 100% is the normal price, but the added 0.07 or 7% should be the sales tax of the base price.

We know this because it is a "rate" multiplying by the base price x.

Furthermore, since the percentage is above 1.00 or 100% (the rate is 107%), then the price of the keg will increase. This must be true because it is a sales tax.

The constant number 17 represents the starting price if there was no tax (or if the base price was x = 0).
