Solar Energy

Did you ever wonder how Solar Energy Panels work?

Renewable sources of energy.

      Solar energy is the solar radiation that reaches the Earth. 

Wind energy is mainly used to produce electricity.

Hydropower is a source of electricity.

Geothermal energy is the heat from the Earth.

 Biomass is organic material from plants and animals.

 

Non-renewable sources of energy.

Non-renewable sources of energy cannot be replaced.

Nuclear Energy is used to generate electricity.
Fossil fuels: 

• Oil

• Gas

• Coal 

Renewable Vs. Non-renewable sources of energy.

Remember! Renewable sources of energy don't polute. What about non-renewble sources of energy??

Uses of energy.

We use a lot of energy in our homes, in businesses, in industry, and for personal travel and transporting goods.

There are four major sectors that consume energy:

• The industrial sector includes facilities and equipment used for manufacturing, agriculture, mining, and construction. 

• The transportation sector comprises vehicles that transport people or goods, such as: cars, trucks, buses, motorcycles, trains, subways, aircraft, boats, barges, and even hot air balloons. 

• The residential sector consists of homes and apartments.

• The commercial sector includes buildings such as offices, malls, stores, schools, hospitals, hotels, warehouses, restaurants, places of worship, and more. 

Water habitats

• Pond: Small area of fresh water. The water doesn't move. Many plants live in and around the ponde. There are fish, forgs, turtles, ...

Rivers and streams: Fresh running water. They are the habitats for many kinds of animals and plants.

• Oceans and seas: saltwater habitats. They are the habitat for algae, fish, mammals, birds, invertebrates, ...

Population and community.

A population of animals is a group of animasls of the same type living in the same place (or habitat).
A population needs water, food and shelter to live.

A community include all the organisms living in the same place (or habitat).

Adaptation

An adaptation is a way an animal's body helps it survive, or live, in its 

habitat.

Land Habitats

Land habitats:

• Deserts: they are dry, hot during the day and cold at night. Organisms vave to adapt to difficult conditions.

• Grasslands:  low rainfall, hot summers, cold winters. There are few trees. Habitat for zebras, lions, cheetahs or antilopes.

 

• Rainforests: they are wet, sunny and warm places There is a rich wildlife. 

• Forests: habitats with trees. Two types of trees:

a) Deciduous trees: they lose their leaves in autumn.

b) Evergreen trees: they have leaves all year long.

• Arctic Region: low temparatures and low rainfall. Animals and plants are adapted to low temperatures.
