Using What We Have Learned

Build Up and Breaking Down

Summary 1

Have you ever seen mountains in the distance?
But you know how is a mountain made?
As the crust (the first layer of the earth) move  the rocks of the crust change.
They can change position they can move up, down ,or sideways .Rocks can also change their shape.
Bu how that happen? by: weathering and erosion.
Weathering: is the breaking down of rocks into small pieces.
Erosion: is the picking up and removal of rocks fragment and others particles.
Weathering example: plant ,wind, animal, acid .
Erosion example: minerals, rocks.

Lift, Carry, and, Drop

Summary 2

Many processes are at work changing the shape of Earth’s surface.                                                         These forces act like a sculptor’s tools. Even while forces are building mountains in the crust  process are at work chiseling into them and wearing them down.

We are going to see how does lift carry ,and drop work

Gravity is always pulling things from high places. This down hill movement of Earth material caused by gravity is called mass wasting ,it depend largely on how deep a slope is. It can happen slowly, particle by particle ,over years.

The sediment is dropped off at the bottom of the hill or at places where the hill becomes less steep called deposition.

The Rock Cycle

Summary 3

Have you ever wondering where a rock came from?                                                          What kind of processes form a rock?

·         First the rock forming from molten material that called igneous rock, they form when hot liquid rock material cools and hardens into solid.

·         Second the rock form from pieces of other rocks that are squeezed called sedimentary rock.

·         Third the rock form from another kind of rock is changed by heat pressure or by chemical reaction called metamorphic rock.

·         And then the rock continually change this is a never ending process called rock Cycle

Geologic Time

Summary  4

Did you know how to find the rock age  is easy .                                                                           Finding  the age of rocks is based on two ideas.

·         Original horizontally this idea explains  that sedimentary rocks forms in the horizontal layers.

·         Superposition in a series of rocks layer the bottom layer is the oldest ,the tpo layer is the youngest                                                                                                                                   Using this two ideas , scientist try to determine the relative age.

Learning About Heredity

Summary  5

What are some characteristic that plants or animals might pass along to their offspring?

 We know that the young usually resemble   their  parents but no exactly.                                      How  characteristic passed from parent to child ?A characteristic  that is passed  from parent to offspring is called an inherited trait. Heredity is the passing of these traits from one generation to the next . The word generation refer to  parents and offspring  parents are one generation, the offspring are another.   Heredity applies to all organism including plants animals, and even bacteria. Fur color is an inherited trait passed from cats to their kittens. Humans have inherited traits too .          

Predicting traits

Summary 6

What refer when someone says predict traits this mean that the parents have a offspring they want to know what trait it will have to the father , to the mother or maybe inhered from their other generations  , but this is only refer to an specific trait first we have to know who is the dominant who their traits will show physically in the offspring , and recessive that it trait is in their sex cell when it reproduce the grandchild will inhered. And then you make a square in the top is male put is if dominant(R R), reccesive (r r) or hybrid(Rr).Hybrid is when is dominant and recessive           

How Heredity Works

Summary 7

In the cells when have the nucleus inside the  nucleus we have chromosomes . That is the human sex cells and whe have 23 chromosomes and they contain an specific trait each inside this we have DNA, Contains  the code that tell to each cell how to operate. The DNA organism is not the same from the others organism
