------------ is the envelope of air around the earth.

Atmosphere
Biosphere
Hydrosphere
Lithosphere

Correct Answer

A. Atmosphere

Explanation

The correct answer is atmosphere. The atmosphere is the envelope of air that surrounds the Earth. It is composed of different layers, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The atmosphere plays a crucial role in protecting and sustaining life on Earth by regulating temperature, providing oxygen for respiration, and filtering harmful ultraviolet radiation from the sun.

The study of weather is called-----------

Meteorology
Ecology
Archaeology
Sociology

Correct Answer

A. Meteorology

Explanation

Meteorology is the study of weather patterns, climate, and atmospheric conditions. It involves analyzing and predicting weather phenomena such as temperature, precipitation, wind patterns, and atmospheric pressure. This field of study is crucial for understanding and forecasting weather events, which helps in making informed decisions related to agriculture, transportation, disaster management, and various other sectors. Ecology is the study of the relationships between organisms and their environment, archaeology focuses on studying human history through artifacts, and sociology deals with the study of human society and social behavior.

---------- is used to measure pressure in the air.

Barometer
Thermometer
Anemometer
Wind vane

Correct Answer

A. Barometer

Explanation

A barometer is used to measure pressure in the air. It consists of a glass tube filled with mercury or a liquid, with one end sealed and the other end open to the atmosphere. As the air pressure changes, it exerts a force on the liquid, causing it to rise or fall in the tube. By measuring the height of the liquid, the air pressure can be determined. Barometers are commonly used in weather forecasting to monitor changes in atmospheric pressure, which can indicate the likelihood of rain, storms, or other weather conditions.

The compositon of oxygen in air --------

21%
78%
1%
0.03%

Correct Answer

A. 21%

Explanation

The composition of oxygen in air is 21%. This means that out of the total volume of air, 21% of it is made up of oxygen. The remaining percentage is made up of other gases such as nitrogen, carbon dioxide, and trace amounts of other gases. Oxygen is essential for the survival of most living organisms, as it is used in the process of respiration to produce energy.

Wind energy is a form of -------------- energy.

Wind
Cycle
Renewable
Solar

Correct Answer

A. Renewable

Explanation

Wind energy is a form of renewable energy because it is generated by harnessing the power of wind, which is a natural resource that is constantly replenished. Unlike fossil fuels, which are finite and non-renewable, wind energy can be continuously produced as long as there is wind. This makes wind energy a sustainable and environmentally friendly option for generating electricity.

March 2
April 18

Correct Answer

A. September 16

Explanation

World Ozone Day is celebrated on September 16 each year to commemorate the signing of the Montreal Protocol in 1987, an international treaty designed to protect the ozone layer by phasing out the production of numerous substances responsible for ozone depletion. This day raises awareness about the importance of the ozone layer and encourages actions to protect it.

The atmosphere is divided into ------layers.

Four
Five
Six
Seven

Correct Answer

A. Five

Explanation

The correct answer is five because the atmosphere is commonly divided into five layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has its own unique characteristics and plays a crucial role in the Earth's climate and weather patterns.
