24. Test Questions • Most of the earth’s water is in the oceans. • The water cycle explains how water changes phase as it moves through the earth’s layers (atmosphere, hydrosphere, lithosphere). • Water collects into rivers and streams within a watershed. • Meandering rivers create many erosional and depositional features in arid and humid environments. • Glaciers produce many erosional and depositional features in alpine areas and continental areas following ice ages. • Oceans are salty because of the weathering and erosion of rocks on land. • Acids in water can form caves and Karst topography. • The ocean floor is formed by the processes of plate tectonics. • Ocean waves are energy moving through the water.
