Water Pollution

Water pollution is when you put bottles and other things that will pollute the water

1.       

      Nutrients Pollution: Waste water and the sewers that has nutrient in the water.

If it goes in a body of water it will grow algae and weed. Then it will make the water undrinkable and also clog filters. This can lead to oxygen dissolved in the water. The algae will block the sunlight so the plants underneath cannot get any sunlight. Seaweed is an example so if the algae is blocking it that means that the seaweed will not grow for a while. When the oxygen is low it can kill fish and the marine life in the water. 

2.       Ground Water Pollution: When people put chemicals in the soil. The rain will go push the chemical down underground and creates water pollution. So when people dig wells they will have to get the water cleaned. Ground water pollution is man made. It is from gasoline, oil, road salts and chemicals get into the ground water. Material can move from land surface throw the soil and ends up underground. 

3.       Surface Water Pollution: Where natural water like lagoons and rivers and hazards things comes in the water and it dissolves and that creates water pollution.Surface water is also man made. It is from all the resources in earth. We cause surface water pollution from the resources on earth. It will go to ocean,rivers,lakes. This can be polluted in a number of ways and its called surface water pollution.

4.       Oil Spillage: When the oil gets into the water and it will kill all marine life like fish and it will effect humans because if we eat the fish it is full with pollution. This is also man made. This is made by careless mistakes cause by an oil tanker that leaks oil out into the ocean. That is not the only way it will occur. Sometimes it will also break down and cause oil to leak. Sometimes it will even explode. Sometimes when people are at war the other country will dump oil into the other country's ocean.

Soil Notes

Plants grow from the soil and the plants will feed almost all life on earth. 

The soil dwellers such as bacteria and fungi recycle once-living organisms into nutrients and soil organic matter

Most of them take in oxygen do their work and they give off carbon dioxide.

Soils are more than dirt. Dirt is a mixture of mineral, air, water and dead things

The possibilities are almost endless – bugs, bacteria, fungi, feces, worms and other things.

Soil has history they are unique, colorful and exotic layers give clue to have changed over time

Most of the earth’s land is in thin soil a variable mixture of minerals, air, water and countless living organisms

The earth’s skin is just not one soil each of it has its own story

Soils are alive they are born and breathe just like us

Soils are always created and lost. You can see soil almost anywhere.

Air, Water, Minerals, and organic matter are the basic ingredients of soils.

They occur in many combinations

Roots and organisms need the water and air that fills the space between particles.

Soils forms from deposited or exposed by sediments and things.

Soils develop as parent’s materials ages in place

Soils take it shape as the water moves

Weathering Notes

Weathering 1

Weathering is when rocks break down into the environment near earth surface. When looking at a mountain you will see piles of loose rocks from landslides weathering that has loosened them from the solid rock of the mountain. When you dig in the farm the soil you dig is the natural product of slow gradual weathering of rocks. There are two classes of weathering. Mechanical weathering: this method tear apart rocks by breaking them down. Physical fracture or pull rocks a part. Chemical weathering: this breaks down rocks atom by atom through chemical reaction. When you hit a rock into pieces by smashing it is mechanical weathering. This tear rocks apart by cracking them and they make them even smaller. Water expands when it freezes. When the temperature drops below freezing the upper surface freezes because of the air. Each freezing may wedge open just a tiny amount. Exfoliation is a term that describes peeling of layers like your skin. But for weathering it will peel of sheet of rocks. Crystals are rocks also expand and contract as they hear a cool. It does not expand that far.Rocks are poor conductors of heat. If the rock cannot take the heat it tends to break. Salt crystals grow in rock fracture or in small pores between sedimentary grains can cause rocks to lessen up and break. This happens when salty water gets into the rock of the water produces. Weathering for crystal growth is fairly restrictive there must be ready source of salt water. Ant other wedging is caused by tree roots. They are tiny and penetrate easily into fine fractures of rocks. The roots will grow anywhere. Abrasion is the mechanism of rocks breaking. The rocks will fall off the cliffs and will be left under the ground. Nearly all types of sediments. This could be in cold and wet environments. It need to be in a high elevation. 

Weathering 2

Rock will always wear away. When that happens it is called weathering. There are actually 3 different types of weathering physical, chemical and biological.

Physical Weathering

This weathering is caused by physical changes. So are when changes in temperature, freezing and thawing and the effects of wind and rain. When the rock gets hot it will expand a little when the rock gets cold it will contracts a little. Wind and rain can cause weathering.  The water expands slightly when it freezes into ice.

Biological Weathering

Animals and plants can wear away rocks. When this happens it is called biological weathering. When an animal digs into the ground also known as burrowing it will leave a crack in the rock making it split. When you see weeds grow in a crack of the rock that is because of plant roots. Plant roots can grow in side cracks. They will keep growing and the crack will keep getting bigger and bigger.

Chemical Weathering

The rocks weathered by chemicals is called chemical weathering.  Rainwater is naturally slightly acidic because of carbon dioxide. Minerals may react to rain water and cause the rock to be weathered.
