EVERYDAY SCIENCE

Detailed explanation-1: -Melting of rocks at the impact site, which would have released carbon dioxide into the atmosphere, resulting in greenhouse warming. Increased acid rain from the reaction of water with the sulfur dioxide and carbon dioxide added to the atmosphere by the impact.

Detailed explanation-2: -When an asteroid hits the earth it causes the atmosphere to change. Dust and particles of debris from the collision find their way into the upper atmosphere and have the effect of blocking the sun’s rays. Insolation is reduced and the climate cools because energy from the sun is reflected back into space.

Detailed explanation-3: -Meteorite impacts are catastrophic events, producing shock waves and raising the temperature at impact to thousands of degrees, melting (and even vaporizing) some minerals.

Detailed explanation-4: -The earth’s climate is influenced and changed through natural causes like volcanic eruptions, ocean currents, the Earth’s orbital changes, solar variations and internal variability.
