Energy+in+the+Earth+System

4. Many phenomena on Earth’s surface are affected by the transfer of energy through radiation and convection currents. As a basis for understanding this concept: a. Students know the sun is the major source of energy for phenomena on Earth’s surface; it powers winds, ocean currents, and the water cycle. b. Students know solar energy reaches Earth through radiation, mostly in the form of visible light. c. Students know heat from Earth’s interior reaches the surface primarily through convection. d. Students know convection currents distribute heat in the atmosphere and oceans.

=Solar Energy= =Introduction= Hello this is our science project.We will be talking about Solar Energy. We will also be talking about Electromagnetic Radiation,different kinds of Waves,and Atmosphere. =Vocabulary= Solar Energy:energy from the sun

Electromagnetic Radiation:energy transferred by waves that can travel through empty space.

Waves:a disturbance that transfers energy from one location to another =Electromagnetic Radiation= First we will explain electromagnetic radiation.Electromagnetic radiation is energy transferred by waves that can travel through space. Other different kinds of electromagnetic radiation include radio waves,microwaves,and x-rays. Each different kind of electromagnetic radiation have properties that depend on wavelength. Wavelength is the distance between two peaks of the wave.Electromagnetic waves are important because they can transfer information and energy. =Waves= A wave is something that moves energy from one place to another.For example when a wave moves through the ocean,the water molecules move fastly from thier standing positions.Light waves move through a vacuum,which is empty space.The source of light comes from the sun,the sun makes light because it is very hot,as with all hot things.The speed of light through a vacuum is 300,000 km/s (186,000 mi/s).This is the fastest possible speed in the universe. =Atmosphere= The reason most electromagnetic radiation doesnt hit Earths surface is because the Earths atmosphere blocks it.The atmosphere is a blanket of air that surrounds earth.Atmosphere interacts with solar radiation in a number of ways.In addition,a small amount of ultravoilet and infrared light hits the Earths surface because the atmosphere prevents most of it from doing so. =Conclusion= In conclusion,Solar Energy is a complex topic.Energy in the Solar system is vital to Earths survival.Without the atmosphere we would be nonexistent,and so would the Earth.
