Question

If all of Earth's carbon was eventually buried in its deep rock, life would not be possible on Earth's surface. Besides burning fossil fuels, what brings the deep rock carbon back up to the surface?


hurricanes and tornadoes


rain and floods


volcanoes and earthquakes

Answer 1

The correct answer is **volcanoes and earthquakes**. These geological processes can bring carbon from deep within the Earth back to the surface. Volcanoes can release carbon dioxide and other gases trapped in the Earth's crust during eruptions, while tectonic activities, such as earthquakes, can also lead to the uplift of rock layers that contain carbon. Rain and floods, while they can influence weathering and erosion, do not directly bring deep rock carbon back to the surface in the same way that volcanic and earthquake activity does.
