The radiations that heat earth’s atmosphere, comes from the
a)
Sun
b)
Earth
c)
Ionosphere
d)
Sun and Earth
 | Asha Yadav answered |
The primary source of radiation that heats the Earth is the Sun. The Sun emits electromagnetic radiation, including visible light, ultraviolet radiation, and infrared radiation. As this radiation travels through space, it reaches the Earth's atmosphere and is absorbed, reflected, or scattered by various gases, particles, and surfaces.
The Earth's atmosphere also emits radiation, particularly in the form of infrared radiation, which is re-radiated back towards the Earth's surface. This process is known as the greenhouse effect, and it helps to trap heat in the Earth's atmosphere, making it possible for life to exist on the planet.
Other sources of radiation that contribute to the heating of the Earth include cosmic rays, which are high-energy particles that come from outer space and can penetrate the Earth's atmosphere, and radioactive decay, which generates heat within the Earth's core. However, these sources are much less significant than the Sun in terms of their contribution to the Earth's overall heat budget.

Increase in the volume of carbon dioxide for the past few decades is mainly due to
a)
deforestation.
b)
climate change.
c)
atmospheric composition.
d)
burning of fossil fuels.
 | Somasekhar Kamal answered |
The answer is D. Because, 1. Forests are the sinks for the carbon dioxide. Forests use CO2 in their growth. So, deforestation due to changes in land increases concentration of CO2. 2. The time taken for atmospheric CO2 to adjust to changes in sources to sinks is 20-50 yrs. It is rising at about 0.5 percent annually. 3. In atmosphere CO2 comprises only 0.04 percent. All the above processes are causing the CO2 conc. to increase in atmosphere in small quantities. However, 4. The emission of CO2 comes mainly from fossil fuels combustion (oil, gas, coal). Which causes more and more pollution and led to global warming. (especially during to industrialization period).

Oceanic deeps of submarine trenches:
Deep narrow steep sided depression is found along the abyssal plain.
The depth of these trenches may vary from 6,000 to 11,000 m. Example, Marina trenches is the deepest trench in Pacific Ocean.
Trenches are formed as a result of tectonic forces and normally occur along the marines of Pacific Ocean.
They occur at the base of the continental slopes and along the island area. Normally associated with volcanoes and strong earthquake.
There are 32 trenches in Pacific Ocean, 19 in Atlantic Ocean and just 6 in Indian Ocean.
