Science- Air, Water and Weather Online Practice Exams FAQs

1. What is air made of?

Air is a mixture of gases, primarily composed of: - Nitrogen (about 78%) - Oxygen (about 21%) - Trace amounts of carbon dioxide, water vapor, and other gases. It is essential for life and plays a vital role in various natural processes.

2. How does the water cycle work?

The water cycle is a continuous process that involves the following stages: - Evaporation: The sun's heat causes water from oceans, lakes, and rivers to evaporate and form water vapor. - Condensation: Water vapor rises and cools, condensing into tiny water droplets, forming clouds. - Precipitation: When the cloud particles become heavy, they fall back to the Earth's surface as rain, snow, sleet, or hail. - Runoff: Excess water flows over the land surface and returns to rivers, lakes, and oceans. - Infiltration: Some water seeps into the ground, replenishing underground water sources. The water cycle ensures a continuous supply of water on Earth.

3. What causes different weather conditions?

Weather conditions are influenced by several factors, including: - Temperature: High temperatures result in warm weather, while low temperatures lead to cold weather. - Air pressure: High-pressure systems generally bring clear and sunny weather, while low-pressure systems often bring clouds and precipitation. - Humidity: High humidity levels can lead to muggy and uncomfortable weather, while low humidity can make the air feel dry. - Wind: The movement of air masses can affect weather patterns and bring changes in temperature and precipitation. These factors, along with geographical location, contribute to the diversity of weather conditions experienced around the world.

4. What is the greenhouse effect?

The greenhouse effect is a natural process that keeps the Earth's surface warm. It occurs when certain gases in the atmosphere, such as carbon dioxide and water vapor, trap heat from the sun. These gases allow sunlight to pass through but prevent some of the heat from escaping back into space. As a result, the Earth's surface and lower atmosphere are kept warmer than they would be without the greenhouse effect. However, human activities, such as burning fossil fuels, have increased the levels of greenhouse gases in the atmosphere, leading to enhanced greenhouse effect and global warming.

5. How can we conserve water?

Conserving water is crucial for sustainable living. Here are some ways to conserve water: - Fix leaks and dripping faucets promptly. - Use water-saving fixtures and appliances, such as low-flow toilets and efficient washing machines. - Collect rainwater for gardening and other non-potable uses. - Turn off taps while brushing teeth or soaping hands. - Water plants during the early morning or late evening to reduce evaporation. - Use a broom instead of a hose to clean driveways and sidewalks. Small actions can make a significant difference in conserving this precious resource.
