What you will learn today:  Water is always moving and changing states in nature  Heat creates the water cycle and affects weather  The water cycle and ocean currents depend on convection

Heat Flow in the Water Cycle The Sun’s energy is completely responsible for three extremely effective natural systems that influence the life on Earth -Water cycle -Weather Patterns -Ocean Currents Adding heat to water will cause the water to change from a liquid to a gas When hot steam touches cold air, it condenses, changing from a gas to a liquid Water in the atmosphere isn't always invisible When the temperature is high above Earth starts to decrease, water droplets join together

Weather & The Water Cycle Since the Earth is a sphere, the Sun’s incandescent energy does not constantly fall on Earth’s land and seas All year round, even though space, the Sun directly shines onto the land and ocean at/near the equator, oxidizing them more strongly In Canada, the Sun’s rays fall less direct than at the equator In the winter, Canada receives less sunlight, resulting with Canada being cold and snowy The difference in temperatures between areas near the equator and northern and southern areas set wind across the Earth Cool ocean breezes and cool land breezes

Heat & Ocean Currents An ocean current is a pattern of motion of the water in a large area of the ocean Ocean currents contribute to the movement of thermal energy from the warmer areas on Earth close to the equator to the northern and southern areas in the Arctic and Antarctica An ocean current affects the climate Ocean currents influence the terrain regions that form Canada's eastern, western and northern coasts Ocean currents flow in convection patterns

Keeping it Warm, Keeping it Cool Ocean currents move in a circle pattern clockwise in the northern hemisphere and counter clockwise in the southern hemisphere There are 3 different types of currents * Warm Surface Currents * Cold Surface Current * Deep Ocean Current The ocean is layered: top layer is warm and the bottom layer is cold

Spinning Systems The atmosphere and oceans always move The wind and storms in the troposphere and currents in the oceans Strong winds can be very harmful and might cause hurricanes and tornadoes They are unpredictable, doesn't last long, and in a local area
