Respuesta :

1.Thus, the correct option is B.  Soil is made up of the tiniest rock particles that include decomposed plant and animal debris.

2. Thus, the correct option is D. There are 4 types such as:

  1. Sand: Sand is a type of rock formation. A sand can't hold a plant since it can't hold enough water for its roots to drink, and it also lacks the nutrients that a plant needs to thrive.
  2. Silt. This sort of soil is generally found around sources of water. This sort of soil is made up of sand and mineral particles, and it can help boost fertility.
  3. Clay: A soil in which the particles are closely packed. When moist, this type of dirt becomes extremely sticky and can be molded into any shape. When it dries, it becomes smooth and returns to its original shape.
  4. Loam: The most suitable soil for a plant. This dirt is a mixture of all three types of soil. Its ability to hold water and nutrients makes it ideal for storing plants.

3. Thus, the correct option is B. Clay-rich soils, on average, contain the largest pore space, and thus the greatest total water holding capacity.

4. Thus, the correct option is D. Soil filters water and serves as a growing medium for billions of species, contributing to biodiversity, and provides the majority of antibiotics needed to treat diseases.

5. Thus, the correct option is A. Pots, toys, and statues are all made from clayey soil.

6. Thus, the correct option is D.  Decayed organism like plants and animals make soil fertile and add nutrients to the soil.

7. Thus, the correct option is C. Sand is found on almost every beach. The action of the waves aids in the shaping of shorelines. Waves take sand from shorelines during erosion. Waves deposit sand along shorelines during deposition.

8. Thus, the correct option is D. The intermediate layer of the soil is where we normally find loam. Pulverized soil with an equal quantity of sand and slit is known as loamy soil. It also has clay in it. On the E horizon, there is loamy soil.
