What effect do volcanic eruptions have on the climate?

• They always increase global temperatures.

• They can cool the area by blocking incoming solar radiation.

• They have no effect on the climate.

• They only affect the climate in the Southern Hemisphere.

Answer explanation

Volcanic eruptions can release ash and sulfur dioxide into the atmosphere, which can block sunlight and lead to cooling in the affected areas. This is why the correct choice is that they can cool the area by blocking incoming solar radiation.

What is one impact of meteor impacts on the environment?

• Increase in photosynthesis

• Decrease in temperature and blocking of light

• Increase in agricultural productivity

• Increase in oxygen levels

Answer explanation

Meteor impacts can eject dust and debris into the atmosphere, leading to a decrease in temperature and blocking sunlight. This can disrupt photosynthesis and alter ecosystems significantly.
