THE LAYERS OF THE EARTH

 THE LAYERS OF THE EARTH

Crust

The crust is the thin outer layer of the Earth where we live. Well, it looks thin on the picture and it is thin relative to the other layers, but don't worry, we're not going to fall through by accident anytime soon. The crust varies from around 5km thick (in the ocean floor) to around 70km thick (on land where we live called the continental crust). The continental crust is made up of rocks that consist primarily of silica and alumina called the "sial".

Mantle

The next layer of the Earth is called the mantle. The mantle is much thicker than the crust at almost 3000km deep. It's made up of slightly different silicate rocks with more magnesium and iron.


Outer Core

The Earth's outer core is made up of iron and nickel and is very hot (4400 to 5000+ degrees C). This is so hot that the iron and nickel metals are liquid! The outer core is very important to earth as it creates something called a magnetic field. The magnetic field the outer core creates goes way out in to space and makes a protective barrier around the earth that shields us from the sun's damaging solar wind.

Inner Core
The Earth's inner core is made up of iron and nickel, just like the outer core, however, the inner core is different. The inner core is so deep within the earth that it's under immense pressure. So much pressure that, even though it is so hot, it is solid. The inner core is the hottest part of the Earth, and, at over 5000 degrees C, is about as hot as the surface of the sun.

COMPOSITION OF THE EARTH

Composition of the Earth.

The Earth is made up of a number of parts, some of them are constantly moving!

You can think of the Earth as being made up of a number of layers, sort of like an onion. These layers get more and more dense the closer to the center of the earth you get. See the picture below to see the four main layers of the earth: the crust, mantle, outer core, and inner core. 

MY CITY: SALTO

SALTO

 

Salto, Uruguay: where is it?

Salto is a very attractive Uruguayan department located on the eastern coast of the Uruguay River, in front of the Argentinean city of Concordia. The city of Salto is the capital of the department, Built near the falls where the Río Uruguay makes its ‘big jump’ (Salto Grande), Salto is Uruguay’s second-largest city.

Its hot springs

The department of Salto has several amazing hot spring which are among the main attractions of the region. Salto's hot springs are called Termas del Arapey and Termas del Daymán, they are famous by their relaxing characteristics as well as by its therapeutic proprieties, due to the way their waters combine an ideal temperature, minerals, and a great environment.

4TH GRADE ACTIVITY: RABBITS INFORMATION

Rabbits

Rabbit!
Rabbits are small mammals found in several parts of the world. The most common and well known is the European rabbit. Rabbits live in groups, and all species apart from the Cottontail live in underground burrows, or rabbit holes. A group of burrows is called a warren. Rabbits are herbivores that feed by grazing on grass and leafy weeds.
Fun fact: A male rabbit is called a buck and a female a doe; a young rabbit is a kit
