The correct answer is: A) Limestone.
Red soils are formed due to the weathering of limestone. Limestone is a sedimentary rock that is composed of calcium carbonate. When limestone is exposed to the elements, it weathers and breaks down into smaller particles. These particles are then transported by wind and water and deposited in other areas. The red color of red soils is due to the presence of iron oxide. Iron oxide is a mineral that is formed when limestone weathers.
Ancient metamorphic rocks are formed when igneous or sedimentary rocks are subjected to heat and pressure. Recent volcanic deposits are formed when magma erupts from a volcano. Sandstone is a sedimentary rock that is composed of sand-sized grains of quartz.
Here is a more detailed explanation of each option:
- Option A: Limestone is a sedimentary rock that is composed of calcium carbonate. When limestone is exposed to the elements, it weathers and breaks down into smaller particles. These particles are then transported by wind and water and deposited in other areas. The red color of red soils is due to the presence of iron oxide. Iron oxide is a mineral that is formed when limestone weathers.
- Option B: Ancient metamorphic rocks are formed when igneous or sedimentary rocks are subjected to heat and pressure. Metamorphic rocks are not typically red in color.
- Option C: Recent volcanic deposits are formed when magma erupts from a volcano. Volcanic rocks are not typically red in color.
- Option D: Sandstone is a sedimentary rock that is composed of sand-sized grains of quartz. Sandstone is not typically red in color.
