Lesson plan n°7 – Spanish version

Hi guys!

Welcome to your natural sciences class!

In this section you’re going to learn about "

the parts of the earth and its layers such as:

the geosphere, the hydrosphere, the biosphere,

the magnetosphere and the atmosphere.

Remember that the earth is the planet we live on, the third of eight planets in our solar system and the only known place in the universe to support life. It is composed of five layers that you can know below.

The Geosphere

The Geosphere is the solid inner part of the earth; that is to say the rocks, minerals, and landforms of the surface and interior.

The geosphere was generated

from the earth formation,

4.6 billion years ago, when the initial

temperature of the planet

was extremely high.

The geosphere is made up

of three concentric layers, called:

the core, the mantle, and

the earth’s crust.

The dense materials sank in the

center, forming a

core rich in iron and nickel.

The lighter magma rose to the surface,

forming the thickest layer on Earth

called the mantle.

Eventually, the outermost

magma cooled to form

the thin layer that we call,

the earth's crust.

The Hydrosphere

The Hydrosphere is the totality of the water of our planet; including the groundwater, surface water and the vapor of water circulating through the air.

The origin of the hydrosphere

is due to at the beginning, the

earth was extremely hot and

the volcanoes emitted gases

among which was water vapor.

It was just as the oceans formed, where the first form of aquatic life emerged millions of years later.

The water is constantly moving in the atmosphere and the surface of the earth and its state (solid, liquid or gas) can change…

This is known as the water cycle, which consists of four components such as: precipitation, collection, evaporation and condensation.

Precipitation occurs when the cloud’s

waterfalls on the grounds as rain,

snow, sleet or hail.

Collection occurs when the roots in the soil

attract the water of the plant through

the stem; and then, the plant uses it for its

metabolic processes until it releases part

of it as a vapor through the leaves.

Evaporation occurs when the liquid

water from ocean surfaces,

rivers, lakes, streams, seas

and puddles turns to steam.

Condensation occurs when water

in a solid state (ice) is transformed

into a liquid state.

The Biosphere

In the biosphere we find the living beings; all the microbes, plants and animals are somewhere in this earth’s layer.

The biosphere is formed for

the layers of the earth. The layer

of the solid surface is the lithosphere,

the atmosphere is the layer of the air which…

extends above the lithosphere

and the water of the earth,

which can be found in the surface,

on the ground or in the air,

forms the hydrosphere.

The biosphere is everything that surround us; for example: the oceans, the continents, a coral reef, a home garden, etc.

It is important to protect the biosphere

avowing the use of harmful chemicals,

the deforestation, the pollution, etc.

and a way to do it is recycling,

reusing and renewing.

The Magnetosphere

The magnetosphere is the magnetic field that extends from the interior of the earth into the space, where it meets the solar wind (a stream of charged particles emanating from the Sun).

The origin of the magnetosphere is

due to the depth of the earth’s solid

iron core, which is as hot as the sun.
