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.

Girl Rising Note Taking


Questions I asked
1. What was Wadley’s mom’s job?
2.  How many countries did they go to help these girls?
3. How long did it take to put this film together?
4. Are we the only school who had watched girl rising?
5.  Why did the girl from Egypt have to wear the thing head?
6. Also why did she have to be silenced?
7. When the super girl killed the man then she got raped?
Note Taking

Why did the police take the houses down when they were living on the street? People should not life on the road so the police have the right to take their tent down. It is not her property.

Wadley’s mom sold potato chips

She had to cover her body with the cloth and be silenced because of their religion.

How did they choose the girl to be on the radio when she was not even educated? She was educated and she went to school.

Jasmine wanted to be strong so she told the police she got raped but she is still stood strong.

Girl Rising - Wadley in Haiti

This is her quote that she wrote "I will come back everyday until i can stay" 

Wadley was only 7 years old when the Haiti earthquake came. It had destroyed her home and her school. Haiti is near Miami. There was a huge earthqquake in 2010 that had destroyed most of Haiti. There was not much if a food supplies. Wadley Story won the Academy Award. Now Wadley is back in school learning.

Polar Vortex Mini Research (Sean 7B)

In the USA and Canada there is this thing going around called the Polar Vortex. it has been very cold in those country's. It has at  -30. That is a all time world record. Russia and Europe have been getting more warmer. They have been getting this snow storm and strong winds after New Years. It is so bad that they had to stop planes from going any where. The airplanes are not allowed to fly now because it will be very dangerous and risky. They also had to stop the trains. It is also causing global warming. This is mainly happening in New York.

Note Taking Earthquake

Continental drift is the hypothesis that states continents on one formed single land mass, broke up, and drifted to the present location
Alfred Wegerner wrote a hypothesis of continental drift
Wegener observed it he calls it Pangaea in Greek it means all earth  
Submerged Mountains run though Atlantic Ocean
Underwater Mountains ''Mid Ocean Ridges"
Sea-Flooring spreading is the process by which new oceanic lithosphere forms as magma rises toward surface
Tectonic plates cause earth quakes in our earth
In the tectonic plates there are other things in side that move
The earth layers can fold,compression and tension
There is also faulting happening in the earths layer
