Convection currents occur in the MANTLE. The mantle is the second layer of the earth after the crust. The mantle is approximately 2900 km thick. Convection currents are triggered or fueled by the heat from the Earth's core.
The part of the mantle closest to the core gets heated. It then becomes less dense than the layers above so it rises. When this rising plume interacts with the crust it cools and becomes more dense than the layers below and so it sinks and this circular motion continues to form convection currents.
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 - d. deciduous forest.
The giant panda lives in the deciduous forested parts of China were the climate is temperate, wet, moisty, and most importantly covered in bamboo trees. The bamboo tree is the only food source of the giant pandas, and it is essential for their survival. Unlike the other bears the giant panda is not an omnivore, and in its evolution due to a genetic mutation it lost its taste for meat and became exclusively a bamboo eater. It is on the verge of extinction nowadays and strict measures are needed for this lovely animal to be protected and preserved.
