Learning about Heredity
We all are alike in comaparation of our parents , dad or mom.
That is why One parent is recessive and the other is dominant.

Geologic Time
You know what is fossil. It is a remain or imprint of a living thing preserved in Earth Crust.
Hard body parts such as teeth ,bones,shells,seeds,pollen grain,and wooden stemof plants are often preserved as fossils . Also earth has more than millions of years existing it has their eras and periods in each one.

The Rock Cycle
One difference that we have to know is what is the Difference between rocks and minerals.
Is a mixture of minerals , that is why is hard to know how many an d what kinds of minerals are in a rock.
While a mineral is compose of one kind , it is poured.
Then other pieces of rocks felll down and accumulate there and it forms sedimentary rock.
Then it compress and then this rock is change by so much heat or pressure it chnage in another type of Rock

Rock Cycle:
All start when eruption in take place in a volcanoe , the lava hardens into solid .Then other pieces of rocks felll down and accumulate there and it forms sedimentary rock.
Then it compress and then this rock is change by so much heat or pressure it chnage in another type of Rock
Lift , Carry and Drop
Lift , Carry and Drop are the three basic words of this topic.
When erosion take place it lift and then some force carry it .
(Forces like plants, animals ,wind,water,ect.)
Then it drop commonly it reached at the ocean bottom.
Also Glaciers are a example of a force.

Building Up and Breaking Down
Earth has an irregular surface because every time it is changing
it is building or making change.
As the crust move the rocks of the crust can change.
The rocks can change position being broken ,twisted or squezed.
That is why the earth make changes the form of the crust.
But always is an end .They are two kind of forces that work to balanced
the Earth crust:
Weathering and Erosion.
That is why it forms layers in the earth because every time an mountain or
something like that it has its end it weather and it falls down forming a mass wasting and one
layer more of the earth. Forming one of the layers of the earth :
Topsoil, Subsoil , Bedrock.
