densk [106]

Answer: mechanical weathering

Explanation:

Weathering is the breaking down of rocks into small fragments or pieces by agent such as animals,water, wind. Erosion helps in the transport of this materials from its region to another.

Mechanical weathering is also known as physical weathering, it causes rocks to crumble as a results of disaggregation of rocks which could results from cracks, freeze thawing.

Water is an important agent of mechanical weathering, in either liquid or solid form.

Liquid water can seep into cracks and crevices in rock as in the case of Lurray Caverns in Virginia,and rock fragments will be eroded this materials accumulation of this leads to a new formation of calcite. If temperatures drop low enough, the water will freeze creating an expansion in the rock that could results in a crack or fragments of rocks falling off.

Nat2105 [25]

The correct answer is option (A) trichomes.

Trichomes are the fine extensions from the epidermal surfaces covering the plant body. They are the result of epidermal cell division. They can be unicellular, multicellular and even glandular. They are characteristically  present on the epidermal surfaces of leaves and roots. They reflect the solar radiation and help in mainitaining the internal temperature and reducing water loss. In roots, they absorb water and minerals and in leaves, they reduce water loss, lower the plant temperature. Plants may use trichomes to detect herbivore attacks as a defense mechanism.
