It's a form of weathering. If water gets into a crack in a rock and then freezes, it will expand, causing the crack to get bigger, which can happen continuously.

I hope this is the type of answer you wanted. :)

i can help you with a lot jus add me

ANSWER:

Water seeps into cracks in rocks, freezes, then expands (since ice occupies a slightly larger volume than liquid water). This expansion pushes the sides of the cracks further apart. ... Rocks can slowly break down by a mechanism known as freeze-thaw weathering, or alternatively, frost wedging.

the stratosphere is the layer of the earths atmosphere that is more than 10 km and less than 50 km which of the following inequa

Gwar [14]

The correct option is (D) |x - 30| < 20.

<h3>What is stratosphere?</h3>

A part of the atmosphere on Earth is called the stratosphere. As you ascend, it is the second layer of the atmosphere.

The stratosphere is immediately followed by the lowest layer, the troposphere. The mesosphere is the stratosphere's superior layer after that.

Calculation for the inequalities given for the stratosphere layer:

According to the question,

The stratosphere is the layer of the Earth's atmosphere that is more

than 10 kilometers (km) and less than 50 km above the Earth's surface.

Consider option D.

|x - 30| < 20

The two cases for the modulus function will be-

Case 1: For positive value of modulus function.

+ (x - 30) < 20

x - 30 < 20

x < 20 + 30

x < 50; which satisfies the condition the stratosphere is the layer less than 50 km above the Earth's surface.

Case 2: For the negative value of modulus function:

- (x - 30) < 20

- x + 30 < 20

30 - 20 < x

10 < x (or)

x > 10; which satisfies the condition the stratosphere is the layer is more

than 10 kilometers (km) .

Step2247 [10]

1. Atlantic

The Amazon river eventually meets the Atlantic Ocean, releasing up to 300 000 square meters per second during the rainy season.

The turbulent Atlantic is directly dumped with freshwater from the Amazon river, making the salinity hundred miles out to sea lower.

2. Marañon (and Ucayali)

The rivers Morona, Pastaza, Nucuray, Urituyacu, Chambira, Tigre, Nanay, Napo, Huallaga, and Ucayali are examples of river systems in Peru that comprise the Marañon River. The Marañon river runs 1000 miles and merges with Ucayali to form the Amazon river.

3. Pará Óbidos

Pará Óbidos is municipality at the swiftest and narrowest part of the Amazon River. It is located 400 miles from the sea, rushing into it at 4 – 5 miles per hour.. It streams single streambed, over 200 feet deep with a width of 1 mile.

4. Brazil

The Lower Amazon, stretching 600 miles from the river’s mouth to the ocean, is located in Brazil. It was the Brazilians that referred the convergence of streams the Amazon River “Meeting of Waters”. Approximately 60% of the river’s basin can be found in Brazil. Two-thirds of the whole Amazon River is part of the country.

5. Peru

The Amazon River’s waters originate from the Andes Mountains and flows through Brazil, Peru, Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana. 60% of the country is comprised of the Peruvian Amazonia. Peruvian Amazonia is the rainforest within Peru’s borders.
