Title 10. UNIT 10. ENERGY SOURCES GV.docx ✅

UNIT 10. ENERGY SOURCES READING I. Read the passage and decide whether the statements are TRUE or FALSE. Wind moves the air. We can work with the power of the wind. Ships on the Nile River were first moved by the wind. Sailboats are still powered by the wind. In the Netherlands, wheat was ground using windmills. Windmills were used by the Pilgrims to grind corn, move water, and power sawmills. Today, we get energy from the wind. The sun gives the wind its power. The sun warms the Earth when it shines. There are places on Earth that are hotter than others. A good example is a place where land and water meet. Most of the time, land can take in and release energy faster than water. The air over land gets hotter than the air over water. When hot air raises, cooler air rushes in to replace it. Wind is the moving air. As long as the sun is out, the Earth will have air. Wind power will always be there. It is a renewable source of energy. No one can own the sun or the air, so it is also free. Statement True/False Wind moves the air. True Ships on the Nile River were first moved by the wind. True In the Netherlands, wheat was ground using windmills. True The sun gives the wind its power. True As long as the sun is out, the Earth will have air. False the explanations for each statement: 1. Wind moves the air. This statement is true. Wind is the movement of air caused by differences in air pressure. When air moves from high pressure to low pressure, it creates wind. 2. Ships on the Nile River were first moved by the wind. This statement is true. Ancient Egyptians used sails to harness the power of the wind to move their ships along the Nile River. 3. In the Netherlands, wheat was ground using windmills. This statement is true. The Netherlands has a long history of using windmills for various purposes, including grinding wheat into flour. 4. The sun gives the wind its power. This statement is true. The sun plays a major role in creating wind by heating the Earth’s surface unevenly, which causes differences in air pressure and creates wind. 5. As long as the sun is out, the Earth will have air. This statement is false because air exists on Earth regardless of whether the sun is out or not. The sun does play a role in creating wind, but it is not responsible for the existence of air on Earth. Air is a mixture of gases that make up the Earth’s atmosphere and it will exist even if the sun is not shining. II. Read the passage and choose the correct answer. Energy is always available to us, making it easy to forget where it comes from and how valuable it is. You might have heard adults telling you to turn off lights or close the fridge door, but have you ever wondered why? Each year, we use more energy than the year before, and much of it is wasted by using too much or not using it wisely. Wasting energy isn't good for the environment or our wallets since the electricity bill goes up. Most energy sources we use, like coal and natural gas, can't be replaced once used up, and many forms of energy cause pollution. Kids can help by turning off lights or closing fridge doors when not needed, and saving energy is like saving money. Every little action helps in saving energy and making a better world. 1.
