The pressure of the dam's water storage increases with depth. Therefore, dams have a broader bottom to handle the increasing water pressure.
Write a short note on the purpose of a dam.A dam can stop or restrict the flow of surface water or underground streams. Dams result in reservoirs that provide water for flood control, aquaculture, irrigation, human consumption, and navigation. Hydropower and dams are frequently used in conjunction to produce electricity. A dam may also be used to collect or store water that will be evenly dispersed among numerous locations. Dams typically serve the primary function of retaining water while other structures, such as floodgates or levees, are used to control or limit water flow into specific geographic zones.
The following are a few dam's intended uses:
Water supply : The reservoirs of the dam provide enough high-quality freshwater to service residential, commercial, and mining regions.Irrigation : Water kept behind dams is utilized to irrigate crops in many different countries.Dams are required for the hydroelectric power plants to produce electricity.Flood control : Mankind has built dams for thousands of years to help stop major floods. It makes the loss of life and property less likely. Before being released into the river below the dam, stored, or redirected for use elsewhere, floodwaters are held back by flood control dams.To know more about, dams, visit :

Answer:

Explanation:
which of the following can be used as evidence that the observed increase in atmospheric co2 is caused by humans burning fossil fuels (select all that apply) group of answer choices
The combustion of fossil fuels raises the amount of CO2 in the earth's atmosphere, which may contribute to the phenomena known as acid rain.
The globe really cools due to air pollution, which is mostly brought on by the combustion of fossil fuels, as some incoming solar energy is reflected. If airborne pollution were to be reduced, it's likely that there would be a brief rise in temperature. Overall, cutting back on air pollution would save trillions of dollars and millions of lives, making it well worth the benefit.

Desalination could be a viable water source for ___________ located near oceans.
Desalination could be a viable water source for water crisis-prone areas located near oceans. This is due to the function of the desalination process which is able to remove excess salt levels in seawater so that it can be used for daily consumption.
Desalination Process and TypesBasically, seawater desalination is a process to remove excess salt levels contained in water, with the end result being water that can be consumed by humans, animals, and plants. In simple terms, the way seawater desalination works relies on filtering it with a special method.
Even so, before the existence of filtering technology, we were also familiar with the seawater desalination process using the vacuum distillation method. In principle, this method utilizes equipment to heat seawater which produces water vapor.
Furthermore, the water vapor that has accumulated will be condensed to produce water that is safer for consumption. However, this method has begun to be abandoned because the operational costs are quite expensive.
Therefore, the presence of a filter method becomes a more affordable solution with an easy-to-use installation system. Currently there are 2 types of seawater desalination technologies that are most often used, namely:
- Reverse osmosis technology, which is used in 47.2% of the desalination system.
- Multi stage flash technology, which is used in 36.5% of desalination systems.

the pacific plate near japan is moving at 92 mm/yr. the eurasian plate in eastern russia is moving at 21 mm/yr. both plates are moving in the same direction. what type of boundary is between them?
A destructive plate boundary is formed. The Pacific Plate, which is thinner and denser, is subducted under the lighter Eurasian Plate into the asthenosphere, where it is melted and destroyed.
The Earth's upper mantle contains the ductile and mechanically feeble asthenosphere. It stretches as far as 700 kilometers beneath the lithosphere, between 80 and 200 km (50 and 120 mi) below the surface (430 mi). The asthenosphere's lower border, however, is not clearly defined.
Although the asthenosphere is nearly solid, its mechanical weakness is caused by a little amount of melting (less than 0.1% of the rock). The most significant source of magma on Earth is when the asthenosphere wells upwards because there is more extensive decompression melting there. It is the source of several magmas that erupted above subduction zones or in areas of continental rifting, including mid-ocean ridge basalt (MORB).

The correct answer is c. Based on the sedimentary rocks structure the sediment must have had flowing currents of water.
Sedimentary rocks reveal details about different surface habitats. Because of this, they may be the most accurate historians of past Earth surface conditions, human presence, and significant events. There are certain processes that occur in each type of habitat that cause a particular form of sediment to be deposited there.

Volcanic ash plumes are frequently photographed by satellites, although usually while they are moving away. Before, people have seen plumes blowing out from Shiveluch. But this picture is different.

Station models are symbolic representations of the weather at a specific reporting station used in meteorology. The station model was developed by meteorologists to accommodate several weather factors on weather maps in a constrained area. This enables viewers of maps to examine trends in factors such as cloud cover, precipitation, wind speed and direction, and atmospheric pressure and temperature. The most frequent station plots show surface weather measurements, while they also regularly show higher air plots at different mandated levels.

In order to represent a northeast wind, a line will be drawn from the cloud circle to the northeast, with flags denoting wind speed at its northeast end. An study of isopach (lines of equal wind speeds) can be carried out once they have been placed on a map.
