Mudflows are the least dangerous type of sediment flow C. mass wasting happens when sediment is carried from a low elevation to a higher one D. in saltation, acids and salt in ocean water dissolve rock minerals

Answers

Answer 1
Answer:

The correct answer is - A. Glacial erosion forms wide, U-shaped valleys.

The glaciers are essentially large masses of ice, formed either by large mas of snow or a frozen river. Because the ice is expanding, but also the glaciers appear at higher places and slowly move towards lower parts, they contribute to a lot of erosion. The size and their weight, plus their movement and the pressure they make, the glaciers manage to erode lot of material, and by doing so, they reshape the landscape in accordance to their form, which is an elongated, river like, U-shape. Once they are melted, the glaciers leave behind them long and narrow U-shaped valleys, some of which remain as a valleys, while others are filled with sea water and formed the fjords.

What is the lithosphere made out of?

Answers

The lithosphere is the outermost layer of the Earth's structure, and it is primarily made up of rocks and minerals.

The lithosphere is a crucial component of the Earth's structure, encompassing both the Earth's crust and the uppermost layer of the mantle.

Rocks in the lithosphere are formed from various minerals. Minerals are naturally occurring inorganic compounds that have specific chemical compositions and unique crystal structures.

Some of the most common minerals found in the lithosphere include silicates, mica, feldspar, and quartz. These minerals combine to create different types of rocks that make up the Earth's crust and upper mantle.

One remarkable feature of the lithosphere is its division into several large and small tectonic plates. These plates are like giant puzzle pieces that fit together.

Thus, the outermost layer of the Earth's structure, known as the lithosphere, is largely composed of rocks and minerals.

How could you identify the unmarked poles of a magnet?

Answers

Answer: A magnet has two poles that is north pole and south pole. From the directional property of the magnet, we know that whenever a magnet is freely suspended, it is always aligned along the north and south direction of the earth.

It can also be identified using a test magnet whose poles are already known. From attraction property of magnet, we know that unlike poles attract with each other and like poles repel each other. Therefore, the pole of unknown magnet that attract to the south pole of the known magnet will be north pole and the other will be south pole.

Thus, by freely suspending the magnet and by using a test magnet, the unmarked poles of the magnet could be easily identified.

You can identify the unmarked poles of a magnet using different techniques.
1) Get a marked magnet to know the north and south poles of the unmarked magnet. North of the marked magnet attracts the south of another magnet.
2) Using a compass - the north of the unmarked magnet aligns tot he north of the compass
