7 Factors influencing atmospheric pressure

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 …

8 ECONOMIC IMPORTANCE OF VOLCANICITY

8 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. Volcanicity on the other hand involves the expulsion of molten lava on the earth surface …

HOW AN OX BOW LAKE IS FORMED

HOW AN OX BOW LAKE IS FORMED

The following are steps on how the ox-bow lake is formed: a river stars to meander on a flood plain lateral erosion occurs on the outer side of the bend while deposition takes place on the inner bank lateral erosion leads in the reduction of the neck of land between adjacent bends the neck of …

4 PROCESS OF RIVER EROSION

4 PROCESS OF RIVER EROSION

The following are the process involved in the river erosion: Hydraulic process this is the eroding force of the water on rocks. This takes place when the force of the river water surges into cracks or sweeping against banks on the outside of bends with turbulence and eddying. It erodes through quarrying or scooping by a …

MEANING OF VOLCANO

MEANING OF VOLCANO

The volcano is the rupture on the crust of planetary mass such as earth, which allows hot lava, volcanic ash, and gases to escape from the magma chamber. Volcanic activities have spread all over the world and can happen both on land and beneath the ocean. Volcanic activities are especially active in convergent and divergent zones …

9 FEATURES FORMED DUE TO WAVE EROSION

9 FEATURES FORMED DUE TO WAVE EROSION

A wave is an up-and-down movement of water. When the wind blows over the ocean, waves are formed. Tides, storms, and earthquakes also cause ocean waves. The force of breaking waves, or waves striking the shoreline, can break rocks into small pieces. They grind against one another and wear down rock particles until they become …
