1. Most of the atmospheric Ozone is found in which layer of atmosphere ?

Troposphere

Stratosphere

Thermosphere

Mesosphere

Answer: Stratosphere

Explanation:

Ozone is found in the Stratosphere.


2. Batholith is a type of ?

secondary pollutant

valley

ocean current

igneous rock

Answer: igneous rock

Explanation:

Abatholith is a large mass of intrusive igneous rock, larger than 100 square kilometers in area, that is formed from cooled magma deep in the Earth’s crust. Batholiths are almost always made mostly of felsic or intermediate rock types, such as granite, quartz, monzonite or diorite.


3. Cirrus and cumulus are types of ______ ?

mountains

clouds

waves

soil

Answer: Clouds

Explanation:

Citrus clouds are wispy, veil-like clouds that form in the upper troposphere while cumulus clouds are stacked, dense and fluffy and they form much closer to the ground.


4. The term ‘monsoon’ is derived from a/an ?

Italian word

Latin word

Arabic word

Greek word

Answer: Arabic Word

Explanation:

The term ‘monsoon’ is derived from an Arabic word ‘mausim’, which means weather.


5. ___ is a naturally occurring phenomenon that is responsible for the heating of the Earth’s surface and atmosphere. ?

Radiation

Global warming

Greenhouse effect

Global heating

Answer: Greenhouse effect

Explanation:

Green House Effect is a naturally occurring phenomenon that is responsible for the heating of the Earth’s surface and atmosphere. The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth


6. The climate of Assam can be described as ?

subtropical humid climate

mountain climate

tropical dry climate

tropical monsoon rainforest climate

Answer: tropical monsoon rainforest climate

Explanation:

With the "Tropical Monsoon Rainforest Climate, Assam is temperate (summer max. at 35–39°C and winter min. at 5–8 °C) and experiences heavy rainfall and high humidity. The climate is characterized by heavy monsoon downpours, which reduces summer temperatures, enabling formation of foggy nights and mornings in winters


7. The centre of a cyclone is a calm area. It is called the _____ of the storm. ?

heart

head

eye

arm

Answer: Eye

Explanation:

The eye is a region of mostly calm weather at the center of strong tropical cyclones. The eye of a storm is a roughly circular area, typically 30-65 kilometers in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather and highest winds occur.


8. The _____ layer is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km (6,200 miles) ?

Ionosphere

Exosphere

Troposphere

Mesosphere

Answer: Troposphere

Explanation:

Different layers of atmosphere are: Troposphere: It starts at the Earth’s surface and extends 8 to 14.5 km high. This part of the atmosphere is the most dense. Almost all weather is in this region, Stratosphere: It starts just above the troposphere and extends to 50 km high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation is in this layer, Mesosphere: It starts just above the stratosphere and extends to 85 km high. Meteors burn up in this layer, Thermosphere: It starts just above the mesosphere and extends to 600 km high. Aurora and satellites occur in this layer, Ionosphere: It is an abundant layer of electrons and ionized atoms and molecules that stretches from about 48 km above the surface to the edge of space at about 965 km, overlapping into the mesosphere and thermosphere. This dynamic region grows and shrinks based on solar conditions. The ionosphere is a critical link in the chain of Sun-Earth interactions. This region makes radio communications possible. Exosphere: This is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km.


9. The _____ layer starts at Earth's surface and extends 8 to 14.5 km high (5 to 9 miles). This part of the atmosphere is the densest and almost all weather is in this region. ?

Stratosphere

Troposphere

Mesosphere

Ionosphere

Answer: Troposphere

Exosphere: This is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km.


10. Above which layer of the atmosphere does the Exosphere lie ?

Stratosphere

Thermosphere

Mesosphere

Troposphere

Answer: Thermosphere

Explanation:

The Exosphere is the outermost layer of the Earth’s atmosphere and lies above the Thermosphere.
