The Half Dome is an isolated mass suspended within the batholithic intrusions. Developed due to vertical jointing, exfoliation, and some glacial activity. Steep face of half dome began to take shape as thin slabs of rock b/w parallel vertical joints were loosened by weathering and mass wasting and fell away layer by layer. Tenaya Glacier cleared away exfoliation debris and talus flowing in direction parallel to trend of vertical joints, removed sheets of rock by plucking . Rounded back of Half Dome formed as curved shells of rock exfoliated
Because cars use oil and oil is a fossil fuel. And when you drive the engine heats up which make the smoke come out of the exhaust pipe and it gets into the air and pollutes which is dangerous for any creature that flies.
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.
