decreasing the availability of natural fuels
None of the bove. Soil erosion occurs due to deforestation, water, wind and tillage of the land farms. It is the removal of the top layer of the soil, and leads to poorer quality of soil, called a soil disruption. This can be avoided by using proper farming techniques and afforestation.
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:
A. near-Earth objects.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
When scientists discuss objects that might hit Earth, the term which they use to describe them as a group is near-Earth objects.
A near-Earth objects can be defined as a small solar system body such as comets and asteroids whose orbit draws it close or in proximity to the earth's orbit due to the gravitational force of attraction of nearby planetary bodies.
Basically, if the closest approach of a planetary body to the Sun is less than 1.3 AU it is considered to be a near-Earth objects.
Hence, near-Earth objects may pose a collision danger to planet earth.
