Causes of Weather(In order of importance)
• Energy from the Sun• The Earth’s Rotation• The Earth’s Revolution and Tilt• Energy from the Earth’s Core
(Volcanic influences)

Most EnergyComes from the Sun
• A little energy comes from the Earth’s Core• Energy comes from the Sun to the Earth via
Radiation

Methods of TransferringEnergy
• Radiation: Energy in the form of electromagnetic waves(or photons)
• Conduction: Energy transferred by matter touching other matter.
• Convection: Energy transferred by moving matter: mixing
