What Do You Know About The Wind

1. What is the name of the scale that classifies the different wind speeds?

Beaufort

Celsius

Fahrenheit

The Beaufort scale is a scale that classifies different wind speeds based on observable effects on land and sea. It was developed by Sir Francis Beaufort in the early 19th century and is still widely used today. The scale ranges from 0 (calm) to 12 (hurricane-force winds) and provides a standardized way to describe and compare wind speeds across different locations.

2. The windest place on earth is Port Martin in Antarctica.

True

False

Port Martin in Antarctica is considered the windiest place on earth due to its location and weather patterns. Antarctica experiences strong winds throughout the year, with average speeds ranging from 40 to 50 miles per hour. Port Martin, located on the coast of Antarctica, is particularly prone to high wind speeds due to its exposure to the Southern Ocean and the strong circumpolar winds that constantly blow in the region. These extreme wind conditions make Port Martin the windiest place on earth.

3. The fastest winds on earth are found in a tornado funnel?

True

False

Tornadoes are known for their extremely strong winds, which can reach speeds of over 300 miles per hour. These intense winds are concentrated within the tornado funnel, making it the location of the fastest winds on earth. Therefore, the statement "The fastest winds on earth are found in a tornado funnel" is true.

4. How is wind speed measured?

Barometer

Anemometer

Hygrometer

Anemometer is the correct answer because it is a device specifically designed to measure wind speed. It consists of cups that rotate when wind blows, and the rotation is used to calculate the speed of the wind. A barometer is used to measure atmospheric pressure, and a hygrometer is used to measure humidity levels. Therefore, neither of these devices is suitable for measuring wind speed.

5. What is wind caused by?

The sun unevenly heating the earth.

Currents from outer space

The clouds moving in the sky

Revolution of the earth around the sun

Wind is caused by the uneven heating of the earth's surface by the sun. As the sun heats different parts of the earth at different rates, air masses with different temperatures and densities are created. This causes the air to move from areas of high pressure to areas of low pressure, resulting in wind. The uneven heating of the earth's surface is the primary driver of atmospheric circulation and the formation of wind patterns.

6. The direction of the wind it measured by

Hygrometer

Barometer

Weather Vane

A weather vane is a device used to measure the direction of the wind. It consists of a freely rotating arrow or figure, often in the shape of a rooster, mounted on a vertical rod. The weather vane is designed to align itself with the direction of the wind, allowing observers to easily determine which way the wind is blowing. In contrast, a hygrometer is used to measure humidity, and a barometer is used to measure atmospheric pressure. Therefore, the correct answer for measuring the direction of the wind is a weather vane.

7. Is wind power Cheap or Expensive

Cheap

Expensive

Wind power is considered cheap because it is a renewable energy source that relies on the natural force of wind to generate electricity. Unlike fossil fuels, wind is abundant and free, which means that the cost of fuel is eliminated. Additionally, the cost of wind turbines and infrastructure has been decreasing over the years, making wind power more affordable and cost-competitive with other forms of energy. As a result, wind power has become an increasingly popular and cost-effective option for generating electricity.
