Andrea reads 20 pages an hour. Which expression below represents how many pages Andrea would read in h hours?A.0hB6.20hC.20 + 60 + hD.20 + h

Answers

Answer:

20h

Explanation:

The proper equation would be 20h, as if Andrea reads 20 pages per hour, you simply multiply by the number of hours she's been reading to find the number of pages she's read.

For example, if Andrea was to read for 3 hours, she would have read 60 pages as 20*3 = 60

a short summary about drought 90words​

Answers

Answer:

Drought is a dangerous condition which decreases the quality of life. It is termed as a natural disaster with harmful effects. A drought usually occurs when a region faces a shortage of water. This is mainly due to lesser rainfalls. In addition, droughts have proven to be fatal for mankind and wildlife as well.

Moreover, drought is the most dangerous for a farmer. As they do not have an ample supply of water, their crops dry out. This becomes a reason for worry as it is their sole income. Furthermore, drought also leads to various other problems for the environment and mankind.

Causes of Drought

Drought is caused due to various reasons. One of the main reasons is deforestation. When there will be no trees, the water on land will evaporate at a faster rate. Similarly, it lessens the soil capacity to hold water resulting in evaporation.

Moreover, lesser trees also mean lesser rainfall which eventually leads to drought.

Furthermore, as the climate is changing, the water bodies are drying up. This results in a lower flow of surface water. Therefore, when the rivers and lakes will dry out, how will the people get water? In addition, global warming is a major cause of this. The greenhouse gas emitted causes the earth’s temperature to rise. Thus, it results in higher evaporation rates.

Subsequently, excessive irrigation is also a great cause of droughts. When we use water irresponsibly, the surface water dries up. As it does not get ample time to replenish, it causes drought.

If you were dying of thirst which river would you drink from a V shaped valley or a U shaped river

Answers

Answer:

U-shaped river

Explanation:

If the option was available to choose from one of the two then the better option would probably be a U-shaped river. This is because these rivers are formed by Glacier movement, meaning that the glaciers themselves create the U-shape and later begin to melt which fills the path made and creates the river. This leads to the water being much cleaner than V-shaped rivers. V-shaped rivers on the other hand are created from erosion caused by the river itself.

Answers

Answer:

Not very good

Explanation:

Since polar bears are built to live in the cold, it would be really hard for than to adjust to anything else

Because of climate change it’s making their habitat melt.. polar bears live in water & in the cold if their habitat keeps melting it will eventually start going down to Miami & it will be under water within a couple centuries.. but pollution is a big cause of climate change that’s why some places use satellite to get energy from the sun because climate change causes the earth to get warmer or the weather to change in places that doesn’t have that weather anyways they live in the cold they aren’t prepared for heat

Describe, in at least five sentences, what mantle convection is and its role in the movement of the tectonic plates, volcano formation and earthquakes.

Answers

Mantle convection - is when the plates move around the asthenosphere and the magma moves in circular patterns due to heat.

Movement of tectonic plates is related to convection currents in the earth's mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

Suppose that you were asked to compare rates of sediment erosion on two land surfaces: a steep, forested mountain slope; and a flat, grassy plain. Which of the following statements about erosion rates at the two locations is correct?

a. Erosion is greater on a flat plain because the gentler slopes

b. Erosion is less because the mountain is covered by a thick layer of clay

c. erosion is less on the mountain because of the abundant rainfall

d. Erosion is greater on the mountain slope because the higher water velocities

Answers

Answer: d. Erosion is greater on the mountain slope because the higher water velocities

Explanation:

The erosion can be defined as the loss of fertile top layer of the soil due to the action of physical agents like water, wind, and others. The mountain slope will offer less resistance against the movement of the materials like soil, sediments, pebbles, stones, and others down the slope. The water will also flow at higher velocity without any resistance on the mountain slope and it will erode the top layer of soil along with other materials like sediments, pebbles, stones, and others.
