is due to changes in atmospheric chemistry. This is as a result of both natural
and human activities such as industrial emission of gases in one location than
the other or even the quantity of greenhouse gases emitted in the atmosphere.
This may cause differences in average yearly temperature for different
locations. Also, natural changes in the sun which affect the amount of incoming
solar radiation may also be responsible for these differences.</span>
Rip currents are mainly caused when the sea is rough and large waves break into the shore. the water from the previous large wave tries to find a weak spot in the incoming wave and when it finds it, the water quickly pulls away from the shore causing dangerous rip currents. This type of currents have caused numerous deaths.
The Midwest is the biggest agricultural region in the United States, and of the biggest in the world. It is a region that has specialized in the production of several crops that are highly demanded on the market, and are used for multiple different things.
The reason why the Midwest has became an agricultural center is that it has very deep and highly fertile soil. The soil is of such a good quality because naturally this region is a grassland, so the enormous amounts of decaying grasses have created a very good soil suitable for growing numerous types of plants.
Unfortunately, converting the region into an agricultural center has caused lot of environmental problems. The grasslands have mostly been destroyed, and with it the habitat of lot of animals. The extensive usage of pesticides and other chemicals has resulted in pollution of the waters. The mechanization used in the agriculture has become one of the major contributors to the greenhouse gases emissions. Because big portion of the region is semi-arid, or only gets sufficient amounts of rainfall seasonally, the aquifers have been depleted.
Obviously true. It revolves all around them.
