Answer:
Land plants evolved from a group of green algae, perhaps as early as 850mya
No they have a negative charge Protons have a positive charge... I remember because P in Positive and P in Proton
Sun to producers to herbivores to carnivores to decomposes etc.
Radiation is the energy transfer in the light from space from the sun to the solar collector.
<u>Explanation:</u>
On the earth itself the solar collector is situated, here energy must travel from sun to the Earth through vacuum, but energy cannot be transmitted through vacuum by either conduction like molecular collision or convection like fluid movement due to difference in densities, as both of the process need medium. Thus energy from sun to the Earth is traveled through radiation carrying electromagnetic waves, many of these are light waves. Thus energy transfer in the light from space from the sun to the solar collector is processed through radiation.
An accompanying diagram is need to answer this question. Mechanical or physical weathering involves the break up of rock into smaller pieces. Mechanical weathering does not change the chemical composition....it is just broken down into smaller pieces.
In frost wedging the constant freezing and thawing will break rocks into smaller pieces. This occurs in temperate mountainous regions.
Salt wedging occurs at coastal areas where ocean water deposits the salt in the rocks. Peeling is also known as exfoliation and this occurs in desert regions rocks constantly contract and expand as the temperature drastically changes.
Biological weathering is caused by plant roots or burrowing animals. Their actions cause rocks to be broken into smaller pieces.
The diagram that does not demonstrate any of these activities is not likely to be mechanical weathering.
