Weathering

The Water Movement Dependent On Traits Of Soil.

Steps Of The Water Cycle / Componets

Part of the water cycle is when water moves through soil.

Weathering occurs when rocks are exsposed to the hydrosphere (Water) and atmososphere (Air)

Permeability -

How fast water moves through a material is Identified as a rate (speed).

Large ground particles have more permeability because water moves them faster.

The better the pores in the soil are alined the better permeability. For example Pumice has poor permeability while a sponge will have good permeability.

Physical weathering (mechanical weathering)

Evaporation- The process which water in liquid form morphs to become an invisable gas called water vapor.

Zone of Aeration-

The better the permeablity a material has the more water will infiltrate it.

Condensation -

Porosity -

Precipitation

Most basic type of weather process. The process makes the volume of rocks decrease and break down.

Changes in the shapes of rocks, typically the rocks will become rounder and smoother.

The water vapor cools and becomes a liquid. It will typically cling to surfaces.

In this zone very little water is present because gravilty will pull the water down to the zone below saturation.

The zone is located on the top of the capillary fringe and zone of saturation.

The amount of space between soil particles. This is measured as a percentage.

Water falling from the sky

in forms of rain, snow, sleet,

or hail.

Transpiration-

In this step water in liquid

form escapes through the

leaves of trees and becomes

a water vapor, similar to evaporation.

Frost Action -

Infiltration / Percolation-

Porosity does not change

with particle size. Meaning

large particles will have equal

pore space as small particles.

During droughts this zone grows and shrinks

during floods.

Weathering in rocks created by the freezing of water into ice.

The process of aeration occurs

in this zone when the pores of

this zone when the pores of the

soil contain water and air.

Since angular particles lock together tightly round particles have more pore space.

Loosely packed materials have more pore space than tighly packed materials.

Well sorted materials (materials of all the same size) particles have more porosity as well.

Run-off-

Water moves through the surface of the earth. Penetrating through various layers until reaching bedrock.

Zone of Saturation-

Precipitation that strikes

the surface of the Earth flows

over land. This tends to be as flooding or as water in rivers or streams.

Run off can occur when the rate of precipitation exceeds the rate of infiltration.

Saturated round has more run-off than unsaturated surfaces because the water has nowhere to go but over the surface as run off.

This zone is the farthest water can penetrate to. The zone can be known as the groundwater /water table. Wells are located in this zone as well.

The zone rests on top of the impermeable bedrock. Certain bedrock is permeable in this case, water can move throughout it and be stored.

The zone of saturation grows

during floods and shrinks during

droughts.

Capillary Fringe-

A small zone on the top of the zone of saturation where water travels up against gravity.

Capillary action works

best with small sediments like clay.

Bedrock -

Source of the inorganics in the soil.
