The true statement is - B. The rock cycle is powered by the movement of tectonic plates.
Almost all rocks on our planet came to existence because of the tectonic activity. The movement of the tectonic plates is enabling the magma from the mantle layer to come to the surface, cool off, and create new layers of rocks. On the other hand, the same process, where there's subdustion zones, is moving the existing rocks down into the mantle layer where they are ''recycled'' in way, and this process is continuing to happen all the time.
The negative impacts of radiation on a country's economy may include :
- Increased rate of mortality
- Destruction of food crops and cattles
- Environmental contamination
- Long term health complications
Radiation has proven to be very useful in medicine, power, defense and other sectors if adequately deployed. However, it's negative impact can also be overwhelming.
Some of the negative impacts of radiation include :
- Radiation could cause death thousand to millions of people within minutes. Such could result from bomb attacks or release of toxic nuclear substances into the environment.
- The effect of radiation does not only pose risk to life, it could also lead to destruction of crops and cattles. Causing famine and unquantifiable losses.
- Nuclear radiation may be so deadly that it renders several Radius or perimeter of an environment inhabitable. Such is the situation of Hiroshima and Nagasaki.
- Nuclear radiation often poses the risk of terminal diseases such as cancer upon exposure .

The correct answer is - grow wheat or oats.
The Great Plains region is a semi arid region. That means that it has relatively low amount of precipitation. Also, the precipitation occurs only in certain parts of the year, and there's relatively long droughts in between. This has led to the Great Plains region to naturally be a grassland. The grasses have contributed with their quick decomposition for a very fertile soil with deep top humus layer. In order to use the soil, the climate conditions, as well as to retain the soil's high productivity, the farmers have mainly orientated towards the farming of crops like the wheat and the oats. They do not require a lot of water, have characteristics that make them suitable for the climate, and their roots and leftovers from the steams are decomposing very quickly which retains the soil's fertility.

Hills are easier to climb than mountains. They are less steep and not as high. But, like a mountain, a hill will usually have an obvious summit, which is its highest point. According to the U.S. Geological Survey, there is no official difference between hills and mountains.
