3. Ozone

Ozone (O₃) in the Earth’s stratosphere absorbs the majority of the Sun’s harmful ultraviolet (UV) radiation.

2. 70 to 320 Watt/m²

Insolation, or incoming solar radiation, varies significantly based on factors such as geographic location, time of year, and atmospheric conditions. This range encompasses the typical values of solar energy received per square meter on the Earth’s surface.

3. 35%

Approximately 35% of the solar radiation that reaches the Earth is reflected back into space by the Earth’s atmosphere, clouds, and surface without being absorbed. This percentage is known as the Earth’s albedo.

1. Longitude

Longitude does not significantly affect the distribution of temperature on Earth. The primary factors that influence temperature distribution are latitude (distance from the equator), altitude (height above sea level), and ocean currents (which can transport warm or cold water, influencing coastal temperatures).

3. Barometer

A barometer is an instrument used to measure atmospheric pressure. It helps in weather forecasting and altitude determination.

4. Equator

Coriolis effect, which causes moving objects to be deflected due to Earth’s rotation, is strongest at the poles and decreases to zero at the Equator.

2. Willy-willies

In the Atlantic and Northeast Pacific, they are called hurricanes; in the Northwest Pacific, they are called typhoons; and in Australia, they are often referred to as willy-willies.

1. Cirrus

Cirrus clouds form at the highest altitudes, typically above 20,000 feet (6,000 meters). They are thin, wispy clouds composed mostly of ice crystals.

3. Oxygen

Greenhouse gases, such as carbon dioxide, chlorofluorocarbons (CFCs), and ozone, trap heat in the Earth’s atmosphere, contributing to the greenhouse effect.

1. Continental shelf

The continental shelf is the gently sloping submerged portion of a continent that extends from the shoreline to a variable distance seaward where water depth is relatively shallow.

4. Auglhas current

The Agulhas Current is a warm ocean current that flows southward along the east coast of Africa, carrying warm water from the Indian Ocean. The West Australian Current, Benguela Current, and Humboldt Current are all cold ocean currents.

1. Producers

In a grassland ecosystem, producers, which are primarily grasses and other plants, are the largest in number. They form the base of the food chain and provide energy for herbivores, which in turn are prey for carnivores and omnivores.

2. Available species

The recognized categories include endangered species, vulnerable species, and rare species.

3. 82°30’ E

This meridian is used as the reference for Indian Standard Time (IST), which is 5 hours and 30 minutes ahead of Coordinated Universal Time (UTC+5:30).

3. 2500 km

The Great Himalayan range extends approximately 2500 km from west to east. This massive mountain range spans across five countries: India, Nepal, Bhutan, China, and Pakistan.

4. Anaimudi

Anaimudi, located in the Western Ghats in Kerala, is the highest peak of the Peninsular Plateau, with an elevation of 2,695 meters (8,842 feet) above sea level.

2. Luni

The Luni River, which originates in the Aravalli Range in Rajasthan, flows southwest and eventually dissipates into the Rann of Kutch in Gujarat.

1. Godavari

The Godavari River is the largest east-flowing river in the Peninsular region of India. It originates in the Western Ghats and flows eastwards across the Deccan Plateau to empty into the Bay of Bengal.

1. Jaisalmer

Jaisalmer, located in the Thar Desert of Rajasthan, experiences extreme temperature variations between summer and winter.

1. 01 June

The onset of the southwest monsoon at the Kerala coast is typically around 01 June.
