When the water leaks into the ground it may hang on the ceiling of the cave as a droplet. This droplet is known as a minute mineral particle. As the droplet evaporates, it deposits the calcite on the ceiling or the floor of the cave. The next droplet that leaks in will create a build up of the calcite. This build up is what forms the stalactite or stalagmite.
Although the dam produces a huge amount of energy for China it has created many problems. The initial main purpose of dams was to control flooding until hydroelectric technology was invented. China has a lot of hydroelectric potential that should be harnessed reasonably. In the case of the TGD (Three Gorges Dam) China is trying to harness too much waterpower by building a mega dam. The TGD produces 18,000 megawatts of electricity, which amounts to 11% of China’s electricity.
Shale, siltstone, sandstone, and conglomerate. Mineral solutions form chemical sedimentary rocks. They are classified by thier mineral composition. Rock salt, rock gypsum, and crystalline limestone are common chemical sedimentary rocks. Organic sedimentary rocks are made up of organically derived sediments.
A rock is made up of minerals. The tectonic plates cause rock to be pushed and pulled. They are constantly being recycled. The rock cycle is an ongoing process. Igneous rocks can form in two environments that are very different.
Where do these rocks come from? Sedimentary rocks come from the very thing they are named after; sediment. These rocks originate from weatherization and a few other processes over a long period of time. For example, if a mineral is stripped from some rocks during weatherization and are carried to a body of water, the minerals will eventually settle at the bottom of the lake and through some other processes settle down and form rocks (Murck, Skinner, & Mackenzie, 2008). Dead plants and animals, along with minerals already at the locations help to create the sedimentary rocks and their unique characteristics.
Nutritious food is also difficult to get in the Central African Republic. 1. The people of Central African Republic are facing an extreme water crisis. Not only this, but the lack of basic infrastructure and political instability contributes to being an LEDC country. There is a lack of time, money, people and skills to find or filter clean water.
The loss of automatic transmission fluid is only possible through the failure of sealing components such as gaskets, o-rings, and shaft seals. Over time, the rubber parts of the seals may become dry rotted and crack. This can cause the fluid to leak out of the transmission. When the fluid level drops too low, the hydraulic components become unable to supply the pressure needed to lock the clutches and bands in place. When the clutches and bands can’t fully lock the shafts in place the transmission begins to slip.
Commercial farmers produce the vast majority of soybean consumed in the world. This is mostly done
With reference to an area that you have studied, describe and explain the appropriateness of flood management strategies? (15marks) The Three Gorges dam on the Yangtze River in China can seem a very appropriate strategy of flood management however there are some negatives that show that is not a full proof strategy. The Three Gorges dam was built in 1994 to try and reduce major flooding in cities such as Wuhan and Nanjing. It is 101m high and as well boasts the largest hydroelectric power station in the world with around 26 turbines. Behind the dam is a reservoir which can hold up to 22km³ of water, this act as a catchment are for flood water.
Some countries, such as Ethiopia and Kenya, suffer from water scarcity meaning there is a major lack of rainfall and physical factors, such as climate, mean water supply is extremely low. However, some countries, such as Mexico, do not have access to clean, uncontaminated water and suffer from water stress. The reasons for this insecurity include physical reasons, over abstraction, poor access to water supplies, pollution, demand and conflict over major, international rivers. In this essay, I will discuss why these reasons cause some countries to feel insecure, and why others don’t. Firstly, we can look at how physical reasons cause insecurity.
