Answer: Sunlight ↔ Photovoltaic panels, Wind ↔ Wind turbines, Flowing water ↔ Hydroelectric dams, Heat from inside the Earth ↔ Geothermal power plants
💡 Each clean source needs a special technology to turn its energy into electricity without burning fuel.
Answer: Barometer ↔ Air pressure, Anemometer ↔ Wind speed, Thermometer ↔ Temperature, Rain gauge ↔ Amount of precipitation
💡 Weather stations combine the readings of these instruments to forecast the weather.
Answer: Cirrus ↔ Thin and feathery, made of ice crystals high up, Cumulus ↔ Puffy like cotton on clear days, Stratus ↔ A flat gray layer covering the sky, Cumulonimbus ↔ A giant thundercloud that causes lightning and hail
💡 Clouds are classified by their shape and height, and the cumulonimbus stretches vertically for many kilometers, causing storms.
Answer: Water evaporates from the seas and land, then The vapor rises and cools high up, then The vapor condenses into droplets around dust particles, then The droplets merge and grow, then fall as rain
💡 Droplets need tiny particles to condense around, then they collide and merge until they are heavy enough to fall.
Answer: The Montreal Protocol, then The Kyoto Protocol, then The Paris Agreement, then The Saudi Green Initiative
💡 The Montreal Protocol was signed in 1987, Kyoto in 1997, and Paris in 2015, and the Saudi Green Initiative was announced in 2021.
Answer: The troposphere, then The stratosphere, then The mesosphere, then The thermosphere
💡 We live in the troposphere, where weather happens, followed by the stratosphere, which contains most of the ozone, then the mesosphere, then the thermosphere.
Answer: Walking or cycling for short distances, Using energy-efficient appliances, Installing solar panels on the roof
💡 Every bit of electricity or fuel we save means fewer greenhouse gases, while waste increases emissions for no benefit.
Answer: Establishing nature reserves, Banning overhunting, Planting native plants
💡 Reserves, banning hunting, and native plants preserve creatures' habitats, while foreign species may crowd out native creatures.
Answer: Melting glaciers on land, Seawater expanding as it warms, Melting of the ice sheet over Greenland
💡 Melting ice from land adds new water to the seas, and warm water expands to take up more space.
Answer: Overgrazing, Cutting down trees and gathering firewood, Long droughts
💡 Overgrazing and woodcutting strip the soil so the wind blows it away, while tree planting and reserves restore vegetation cover.
Answer: Solar energy, Wind energy, Hydroelectric energy
💡 The sun, wind, and flowing water renew constantly, while oil and gas are fossil fuels that take millions of years to form.
Answer: Carbon dioxide, Methane, Nitrous oxide
💡 Carbon dioxide, methane, and nitrous oxide trap heat, while oxygen and nitrogen, though plentiful, trap almost none.
Answer: True ✔
💡 Overgrazing, cutting down trees, and poor irrigation are human-made causes of desertification, alongside drought.
Answer: True ✔
💡 The oxygen we breathe has molecules of two atoms, while ozone is made of 3 oxygen atoms.
Answer: True ✔
💡 Methane is much stronger at trapping heat, but there is less of it in the atmosphere and it stays there for a shorter time.
Answer: False ✖
💡 Many clouds do not produce rain; rain needs droplets that grow heavy enough to fall.
Answer: True ✔
💡 Trees take carbon dioxide from the air and build their wood with it, keeping it stored as long as they live.
Answer: False ✖
💡 Weather is the state of the atmosphere over a day or a few days, while climate is the usual pattern of conditions in a region over many years.
Answer: False ✖
💡 Solar energy is renewable because the sun rises every day and its light does not run out with use.
Answer: True ✔
💡 Water vapor traps heat in the atmosphere, and its amount increases as the air gets warmer, which strengthens warming.
