The Solar System consists of the Sun and planets that orbit it. There are four inner planets closest to the Sun - Mercury, Venus, Earth, and Mars - and four outer planets farther away - Jupiter, Saturn, Uranus, and Neptune. The Moon is Earth's natural satellite and has four phases as it orbits Earth: full moon, first quarter moon, last quarter moon, and new moon. The document also discusses the atmosphere with its layers of troposphere, stratosphere, mesosphere, and thermosphere, as well as the hydrosphere as the layer of water on Earth's surface and the geosphere with its crust, mantle, and core layers.

4. 2. THE PLANETS.
Mercury, Venus, Earth and Mars are closest to the Sun.
Jupiter, Saturn, Uranus and Neptune are farthest from the Sun.

5. THE MOON
The moon is a natural satellite of the Earth.

6. 3. THE MOON
There are 4 phases of the moon: (Full Moon, First quarter Moon, Last
Quarter Moon and New Moon).
Full Moon. The illuminated side of the moon is facing the Earth. The
Moon is visible

7. 3. THE MOON.
First Quarter Moon: We can see more of the illuminated part of the
Moon´s Surface.

8. 3. THE MOON
Last Quarter Moon: We can see less of the illuminated part of the
Moon´s Surface.

9. 3. THE MOON
New Moon: The dark side of the Moon face the Earth. We cannot see
the Moon.

I have leart……..
What are your opinion about the Universe?

14. ATMOSPHERE.
LAYER OF THE ATMOSPHERE.
Troposphere is the closest layer to Earth.
Stratosphere has the ozone layer that protect.
Mesosphere is the coldest layer
Thermosphere is where falling stars.
Exosphere separates Earth from outer space.

15. ACTIVITY.

16. THE HYDROSPHERE
The layer of water taht covers Earth´s Surface is called
HYDROSPHERE.

17. THE WATER CYCLE.

18. THE GEOSPHERE

19. LAYERS OF THE GEOSPHERE.
The crust: Is the thinnest and outermost layer.
The mantle: Is the middle layer.
The core: This layer has the highest temperatures.
