Water…without it we would not be here! Living Processes – allows us to break down our food, grow, reproduce. This includes ALL plants and animals Habitats
All water on Earth – this sphere is about 860 miles in diameter. Earth's liquid fresh water in groundwater, swamp water, rivers, and lakes. This sphere is about 169.5 miles in diameter. Yes, all of this water is fresh water, which we all need every day, but much of it is deep in the ground, unavailable to humans. Do you notice the "tiny" bubble? That one represents fresh water in all the lakes and rivers on the planet. Most of the water people and life on earth need every day comes from these surface-water sources. The diameter of this sphere is about 34.9 miles. Denver is about 800 miles from Helena to give you some perspective. Yes, Lake Michigan looks way bigger than this sphere (smallest one), but you have to try to imagine a bubble almost 35 miles high—whereas the average depth of Lake Michigan is less than 300 feet (91 meters).

I can describe the cycling of water through Earth’s systems driven by the Sun’s energy and force of gravity. What powers the water cycle (the movement of water through the Earth’s systems)? Step 1: Water vapor enters the air. How? Step 2: Water vapor molecules evaporate into the atmosphere to make clouds. What is evaporation? Step 3: Water vapor molecules condense to form precipitation. What is condensation?
Why is this important? Understand how weather is created and how it impacts our lives. Understand the climate of our region and how it affects us Understand how we can affect the water on our planet.
