THE EARTH'S RELIEF

Internal and external processes change the Earth's relief

INTERNAL PROCESSES

• They cause volcanic eruptions and earthquakes.
• A volcano is created when the magma reaches the surface of the Earth through a crack o fissure. The parts of a volcano are its crater, its main vent and its volcanic cone.
• Earthquakes are caused by the vibrations of the ground moving inside the Earth. This movement is transmitted from a point called the hypocentre.

EXTERNAL PROCESSES

• Geological agents change the Earth's relief. the most important geological agents are wind and water (rivers and streams, sea and ice).
• Geological agents produce erosion, transportation and sedimentation. they create V-shaped valleys and beaches.

ROCKS AND MINERALS

• Rocks are made up of minerals. depending on their origins, rocks can be:
• Sedimentary rocks, like clay. They are formed by compacting deposited material.
• Magmatic rocks. they are formed from magma. They can be volcanic like pumice or plutonic like granite.
• Metaphormic rocks, like slate. they are not melted rocks, but they have been under high pressure and temperatures

NUTRITION

NUTRITION is the function that allows the cells of living things to have the energy and tissues they need to perfurm their functions. Four systems take part un nutrition: the digestive system, the respiratory system, the circulatory system and the excretory system.

DIGESTIVE SYSTEM

It is charge of digestion: it changes food into the nutrients cells need.

RESPIRATORY SYSTEM

• It is in charge of breathing: it takes oxygen from the air that cells need and expels carbon dioxide.
• Breathing has two processes: lung ventilation and gas exchange.



EXCRETORY SYSTEM

• It is in charge of excretion: it eliminates waste substances carried by blood.
• it is made up of the sweat grands of the skin and the urinary tract

"Once upon a time.....the life" THE SKIN

CIRCULATORY SYSTEM

• It is in charge of circulation: it transports nutrients and oxygen to the body's cells.
• It is made up of the heart, blood and blood vessels.
• Human circulation is closed and double.

THE SOLAR SYSTEM

A VERY BRIEF SUMMARY

The Solar System is made up os a star called the Sun and eight planets that orbit around it: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. It also has satellites orbiting around the planets and celestial bodies like asteroids, meteorites and comets

THE LOCOMOTOR SYSTEM

 

A very brief summary

The LOCOMOTOR SYSTEM is made up of the SKELETON and the MUSCULATURE

THE SKELETON

The skeleton is made up of:

• Bones
• Joints
• Cartilage

THE MUSCULATURE

The musculature is made up of all the muscles in the body.

Tendons attach muscles to the bones

Muscles are responsible for movement

TYPES OF MOVEMENTS

• Voluntary Movements: they respond to an order from the brain.
• Involuntary Movements: they respond to an order from:
• Spinal cord: Reflexes
• Brain stem:
