Weather and Climate- 1 - Free MCQ Practice Test with solutions, Class 5

Humidity refers to the amount of moisture in the air. Humid places have more moisture in the air, which can lead to more rainfall and higher levels of humidity.

When the sea is cooler than the land, it makes the air over the sea cooler. This cool air, known as sea breeze, blows from the sea to the land, making the land cooler. This is why places near the sea have a moderate climate, not too hot and not too cold.

Winds that bring rainfall typically originate from the sea, which is a major source of moisture.

Places near the Equator are hotter because they receive more heat from the Sun compared to places away from the Equator. The Sun's rays fall directly on areas near the Equator, making them warmer. That's why these places experience higher temperatures.

• The Earth has three heat zones based on how hot or cold they are.
• The Torrid Zone, the Temperate Zone, and the Frigid Zone are these three types.
• The Torrid Zone is very hot, the Temperate Zone is neither too hot nor too cold, and the Frigid Zone is very cold.
• These zones help us understand why some places are hot, some are mild, and some are very cold on our planet.

When we go up to places at higher altitudes like hill stations, they are cooler than places at lower altitudes. This is because higher places are colder due to being farther away from the warm ground.

Climate refers to the long-term atmospheric conditions of a place, including temperature, rainfall, humidity, and wind patterns, typically averaged over many years.

Winds that blow from cold areas lower the temperature, making the climate cooler. This is why icy winds from extremely cold places can make the climate very cold.

Winter is very dry in many regions because, during this season, winds blow from the land to the sea. These winds carry little moisture since they originate over land, making the air dry. This is why winters are often dry in these areas.

The Torrid zone lies between the Tropic of Cancer and the Tropic of Capricorn, where it receives direct rays of the Sun, making it very hot and humid.

The weather is influenced by several key factors. Here are the main ones:

• Temperature: This affects how hot or cold the air is, which can influence weather patterns.
• Wind: Wind movement can change temperatures and bring different weather conditions.
• Air Pressure: Variations in air pressure can lead to different weather systems, such as storms or clear skies.

Therefore, all these factors work together to shape the weather.

The polar regions, also known as the frigid zones, are the regions surrounding the Earth's North and South Poles and are covered in snow year-round.
