Your class goes on a field trip to observe drilling machinery. The geologists at the drill site show you displays of drilled rocks to compare different types of drills and methods. The drilled holes in one rock display are significantly larger than the holes drilled in the display next to it. Given this information, which statement is correct? (1 point)
Responses
The rock display with smaller holes shows copper drilling, which is deep underground.

The correct answer is A. Soil is considered a vital resource because it plays a variety of roles for plants and animals. Soil is essential for agriculture, as it provides a medium for plant growth and supports the roots of plants. It helps to retain and distribute water, nutrients, and minerals necessary for plant growth. Soil also serves as a habitat for a wide range of organisms, including beneficial bacteria, fungi, worms, and insects. Additionally, soil acts as a natural filter, helping to purify water as it percolates through the ground. Soil erosion can have detrimental effects on ecosystems, agriculture, and even human settlements. Therefore, preserving and conserving soil is crucial for the well-being of the planet and its inhabitants.
To find this answer, you could have eliminated options B, C, and D based on the fact that they do not accurately describe why soil is considered a vital resource. Option B states that soil is hard to destroy and easy to make, which is not entirely accurate. Soil can be easily degraded or polluted, and the process of soil formation takes a significant amount of time. Option C states that soil is the place where all nutrients on Earth are stored, which is not entirely correct. While soil does contain important nutrients, not all nutrients on Earth are stored in soil. Option D states that soil provides the source of material for different landforms, which is not accurate. Soil is formed from the weathering of rocks over time, but it is not the source of material for landforms.
