Clouds, atmospheric aerosols, snow, ice, sand, ocean surface and even rooftops play a role in deflecting the incoming rays. The remaining 70 percent of solar energy is absorbed by land, ocean, and atmosphere. "Greenhouse gases block about 40 percent of outgoing thermal radiation that emanates from Earth," Woods said.

Answer:
The elemental is required in very small amount. (Ans. A)
Explanation:
Trace element is also known as micro-nutrient. It is also defined as any chemical element required by living organisms in a minute or small amounts which is usually part of the vital enzyme (cells produced by catalytic protein).
Exact needs of trace elements vary among species, like commonly required plant trace elements are cooper, zinc, manganese, boron, and molybdenum. Animals commonly required iodine, manganese, and cobalt.
Absence of necessary plant trace elements required by plants in the soil causes deficiency disease, lack of animal trace elements used by animals in the soil may not harm plants, but, animals feeding on those plants develop their deficiency disease.
So, the adjective trace means that the elemental is required in a very small amount.
The *heart* is the main organ of the circulatory system.
The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.
