Teaching English through Geography: Parts of a river
A river is a ribbon-like body of water that flows from high land downhill. It is a geographical feature. Gravity is what causes a river to flow. A river can be wide and deep, or shallow enough. A flowing body of water that is smaller than a river is called a creek or stream. The largest rivers can be thousands of miles long. As the water flows along the river bed the land is worn away, it erodes. Erosion of rivers can form geologic wonders like the Grand Canyon. All rivers have a starting point where water begins its flow, the source. Water can come from rainfall or snowmelt in mountains, but it can also bubble up from groundwater. The other end of a river is called its mouth, where water empties into a larger body of water, such as a lake or ocean. A tributary is a river or stream that flows into another stream, river, or lake. The river loses its velocity as it gets lower and deposits different particles or sediments at its mouth. However, rivers still carry i...
Teaching English through Geography: Water Cycle
Water Cycle Step #1: Water evaporates from the Earth’s surface . If you spill a glass of water outside you will notice that a few hours later the water is gone! That is because water slowly turns from a liquid into a gas called water vapour. The process of water turning from a liquid into a gas is called evaporation. Evaporation happens faster on a hot day. That is because the evaporation of water outside takes energy from the sun! The hotter it is outside, the faster water will evaporate. Since water in its gas form has no colour, we cannot see it. It just goes into the air. Water Cycle Step #2: Water condenses to form clouds Water vapour rises up in the sky due to the sun’s heat. Once the water vapour rises high enough it condenses into water droplets. Condensation is the process of water turning from a gas into a liquid . You have probably experienced condensation if you have had a cold glass of water at a restaurant. As the cold glass sits on the table, water vapour from the...
