Factors influencing atmospheric pressure

7 Factors influencing atmospheric pressure

Atmospheric pressure it is the weight (force) of the air exerted per unit area on the earth’s surface. It is mathematically expressed as:Pressure = Force/Area The weight of air is the vertical column exerted from the upper limit of the atmosphere to the earth’s surface which is approximately 1.034kg/cm3 over the sea level. It is …

Factors influencing wind transportation and deposition

Factors Influencing Wind Transportation and Deposition

The following are Factors Influencing Wind Transportation and Deposition: Wind velocity: when speed decreases strength also decreases and its ability to transport so wind starts to deposit materials. Wind direction- Winds blowing from different directions converge and cause the load to collide causing some of it to be deposited. Nature of desert surface: Wind transportation …

Soil conservation methods

soil conservation methods

The following are Soil Conservation methods Terracing: This is the digging of step-like trenches across a hill, which helps to trap the moving soil hence preventing soil erosion. Crop rotation: This is the planting of different crops on the same piece of land. This helps to control monoculture and its effects. Afforestation and re-afforestation: here, …

Economic importance of volcanicity

Economic importance of volcanicity

VULCANICITY is a process through which molten rocks (magma) are intruded within the earth’s crust or extruded onto the earth’s surface. Vulcanicity is aided by the process of faulting which forms cracks in the earth’s crust through which magma escapes. When magma is intruded within the earth’s crust, it cools down and solidifies to form …

4 types of ground water

4 types of groundwater

Ground or subterranean water is water that is found below the earth’s surface. Groundwater is simply water under the ground where the soil is completely filled or saturated with water. This water is also called an “aquifer.” The following are four types of  ground water: Connate water. It may also referred as fossil water. This …

5 condition necessary for formation of river delta

A river delta is a landform that forms at the mouth of a river, where the river flows into an ocean, sea, estuary, lake, or reservoir.Deltas form from the deposition of sediment carried by a river as the flow leaves its mouth. Over long periods, this deposition builds the characteristic geographic pattern of a river …
