Earth Science

this shows what the earth would look like if we chopped it in half

Types of Rocks & Rocks Cycle Video for Kids by

this shows the rock cycle and how other rocks can change in it others

melting: been where it reaches is melting point and turns into magma or lava

cooling: been where there is snow or cold wether

heat & presser: as in heat plus presser

compacting: just as presser by is self

weathering: like rain, earthquakes, storms and hurricane.

for example and metamorphic can get gridded down and turned into a sediment witch by compacting can get turned into a sedimentary rock.

geology questions and answers.

1.How heavy is the earth?

The earth is 5,972,000,000,000,000,000,000 tones

2.What is the core made of?

The inner core is made of a solid form of iron-nickel

3.What is the crust?

The Earth's Crust is like the skin of an apple. It is very thin in comparison to the other three


4.What are the names of the earths layers?

Crust, mantle, outer core and inner core.

5.What is the outer core made of?

The outer core is made up of a liquid form of iron and nickel.

6.What is the mantle made of?

The mantle is made up of rocks with higher portion of iron and magnesium. And the type of rocks that made up the mantle are mostly olivine, pyroxenes, spinel, garnet, peridotite, dunite and eclogite.

7.How hot is the inner core?

It is 6000°c

8.what’s the circumference of the earth?

The earth circumference of the earth is 24,901 miles (40,075 km)

9.what is the crust of the earth made of?

The crust is made up of different types of rocks; igneous, metamorphic, and sedimentary rocks. did the scientists discover that the earth has layers?

Scientists know about the layers of the earth by sending sound waves through the earth. Because layers of different densities (see earlier question) will allow sound waves to travel through them differently, we can study the sound waves to understand the layers of the earth.
