How Does Energy Move on Earth?

Energy is everywhere! It moves through Earth's systems in lots of ways. The most important source of energy for us is the Sun.

• Sunlight gives energy to plants so they can make food.
• Heat moves from warm places to cool places (like the Sun warming up the ground).
• Energy transfers when animals eat plants or other animals.

Types of Energy Transfer

• Conduction: Heat moves by touching (like your hand warming a cold rock).
• Convection: Heat moves through liquids and gases (like warm air rising).
• Radiation: Heat moves through space (like sunlight).

Why Does Energy Transfer Matter?

Energy helps plants grow, animals live, and weather happen! Learning about energy transfer helps us understand weather, food chains, and even how we use electricity at home.
