Answer:

Crystal size

Explanation:

The most obvious difference between extrusive rocks and intrusive rocks is crystal size. Because extrusive rocks cool quickly, they only have time to form very small crystals such as basalt or none at all. On the other hand, intrusive rocks grow larger crystals because they take longer to cool.

From the standpoint of water availability, which of the four soils; crushed silt loam, aggregate silt loam, fine sand or coarse

earnstyle [38]

Answer:

fine sand

Explanation:

Permeability id a scientific index of the soil to have air and water pass through the soil pore and spaces. As clay soils have a fine texture, with loamy soils moderately textured and sandy soils coarsely textured thus permeability changes from slow to rapid.

As sandy soil is highly permeable i.e 5.0 cm per hour and clay soils having the least i.e 0.05 permeability. Loamy soil is composed of sand, silt, and a smaller amount of clay.

From an agricultural perspective, the soil permeability depends upon the percentage of the see-page and the chemical makeup of the soil. Thus crops can grow more easily this type of soil as the particle size is minute and fine.
