Learning About Heredity

Have you ever heard of purple corn. Corn kernels can be purple as well as yellow. Color is a characteristic that is passed from the parent corn plants to the offspring.It is passed on through the seeds.A characteristic that is passed from parent to offspring is called an inherited trait. Heredity is the passing these traits from one generation to be next.

Geologic Time

Until the mid 1800s most people thought Earth was only a few thousand years old. Today there is much scientific evidence that some of Earth´s rocks are several billions of years old. Telling the relative age of rock layers is not as simple as these two ideas seem to be. Somtimes forces within Eath tilt , fold , or overturn layers of rocks.As people dig into rock layers, they often find fossils. Ossils are any remains , trace, or imprint of living thing preserved in Earth's crust. the era we live in now , the Cenozoic, began about 70 million years ago .

The Rock Cycle

How would you know a rock when you saw one?You would need to know the properties.To begin with, rocks are solid.A rock is a mineral or a mixture of  minerals.Because most rocks are mixtures of  things,they are not as easy to tell apart as indentify a rock is by identifying the minerals it contains.I now tree types of rocks that are: igneous rock,sedimentary rock ,and metamorphic rocks.The igneous rocks form when hot liquid rock material cools and hardens into solid .the sedimentary rock ,Remember that weathering breaks down rocks into pieces of sediment.And the metamorphic rock was another kind of rock that changed . the rocks start out as igneous roks,sedimentary rocks,or even other metamorphic rocks.

Lift,Carry,and Drop

Along moutaintops and hillsides, weathering is breaking  down rock into sediment.they can be
fine bits of clay. It can be larger particles ,such as sand or gravity.How Does Flowing Water Work?
Flowing water makes a powerful force that changes the shape of  Earth´s surface.It can toss loose particles
of rock around and carry them along as it flows downhill.
