Ineed an answer
1. explain the difference between the zone of aeration and the zone of saturation.
2. why is it easier for water to flow through rock and sediment with larger pores than through rock and sediment with smaller pores?
3. how does a cavern differ from a cave?
4. which two factors determine how easily water is able to move through rock or sediment?
5. how do water and carbon dioxide contribute to the formation of karst topography?

1. The one nearest the surface is the "zone of aeration", where gaps between soil are filled with both air and water. Below this layer is the "zone of saturation", where the gaps are filled with water.

2. Larger pores mean less friction between flowing water and the sides of the pores. Smaller pores mean more friction between flowing water and pore walls and more twists and turns for the water to navigate. A permeable material has a greater number of larger, well-connected pore spaces. An impermeable material has fewer, smaller pores that are poorly connected.

3. A cave is any cavity in the ground that is large enough that some portion of it will not receive direct sunlight.

A cavern is a specific type of cave, naturally formed in soluble rock with the ability to grow speleothems.

4. The size of the pores underground rock material has and if the pores are connected

5. Karst regions are formed when there is a chemical reaction between the groundwater and the bedrock. As rain, streams, and rivers flow over the earth's surface, the water mixes with the carbon dioxide that naturally exists in air, and the soil becomes acidic and corrodes the calcium carbonate rock. The carbonate solution seeps into fissures, fractures, crevices, and other depressions in the rock. Sinkholes develop and the fissures and crevices widen and lengthen. As the openings get larger, the amount of water that can enter increases.

answer; i believe that the correct answer is (light);
