Question

Carbon dioxide is added to the atmosphere by several means, one example being volcanic eruptions. Which of the following also adds carbon dioxide directly to the atmosphere. (1 point)
Responses.

burning a forest
burning a forest

forming fossil fuels
forming fossil fuels

evaporation of a puddle
evaporation of a puddle

erosion of igneous rocks

Answer 1

The response that adds carbon dioxide directly to the atmosphere is **burning a forest**. This process releases carbon stored in trees and plants as CO2 into the atmosphere.

The other options do not directly contribute to atmospheric CO2 in the same way:
- **Forming fossil fuels** is a process that takes place over millions of years and sequesters carbon rather than releasing it.
- **Evaporation of a puddle** involves water and does not contribute to carbon dioxide.
- **Erosion of igneous rocks** typically releases minerals and does not directly release carbon dioxide.
