The sun s energy

Climatic interactions exist among Earth, ocean and weather systems.

The Sun provides the energy that drives convection within the atmosphere and oceans, producing winds and ocean currents.


The sun s energy

The energy on Earth comes from the Sun. systems

  • The Sun heats up Earth’s surface and all things on it

  • Matter that absorbs heat energy tends to rise

  • Matter that loses heat energy tends to fall

  • The constant churning of hot and cold is called convection


The sun s energy

Draw what you remember about the Water Cycle. systems

Label: condensation, evaporation, precipitation, transpiration


The sun s energy

Wind is mostly caused by differences in thermal energy absorption

  • Warmer air has less pressure than cooler air

  • The differences in pressure cause movement of air

  • High pressure pushes lower pressure

High pressure sinks because it is more dense.

Low pressure rises because it is less dense.


The sun s energy

Ocean currents are similar to winds absorption

  • Currents are driven by wind at the surface

  • Deeper currents are influenced by temperature and salinity differences

  • Warm water is less dense that cold water

  • Water is more salt is more dense


The sun s energy

A meteorologist studies weather patterns. absorption

  • Uses weather maps to predict weather patterns

  • Weather maps show different air masses, which are areas of air with similar pressure and temperature

  • The boundaries between air masses are called “fronts”

  • The location and movement of fronts are used to predict weather


The sun s energy

Weather Fronts absorption

  • A front is the line of contact at ground level marking the boundary between 2 different air masses.

What is air pressure? which are not moving

  • Air pressure is a measure of the weight or density of the air in a given area

  • Measured with a barometer

  • High pressure = good weather

  • Low pressure = bad weather

  • High pressure sinks

  • Low pressure rises
