Question

Volcanic eruptions, changes in Earth's orbit, meteorite impact, and even the combustion of fossil fuels ALL contribute directly or indirectly to climate change by
A) increasing the amount of ice cover on Earth.
B) changing the amount of solar radiation that reaches Earth.
C) changing the amount of greenhouse gases in Earth's atmosphere.
D) increasing the amount of particulate matter in Earth's atmosphere.

Answer 1

Answer:

B) changing the amount of solar radiation that reaches Earth.

Explanation:

Solar radiation is the energy emitted by the sun that reaches the earth's surface and is vital for our survival in certain concentrations. However, when the concentration of this radiation is above normal, it can cause some damage to our health and the health of living beings in general.

To prevent this, the earth has layers in the atmosphere that protect us from high concentrations of solar radiation. However, volcanic eruptions, changes in Earth's orbit, the impact of meteorites and even the combustion of fossil fuels can degrade these layers and cause serious changes in the planet's climatic conditions.

Answer 2

Climate change refers to the variation in the statistical distribution pattern of weather when that variation endures for an elongated time duration. The change in climate is a result of various elements like biotic procedures, changes in solar radiation received by Earth, plate tectonics, and others.  

The changes in Earth's orbit, volcanic eruptions, combustion of fossil fuels, and meteorite impact, all donate directly or indirectly to climate change by changing the amount of solar radiation that reaches Earth. Hence, the correct answer is option B.
