How can biological weathering result in chemical erosion?

Roots loosen soil and break rocks.
Large herds trample rocks and break up soil.
Plants transpire water vapor.
Bacteria release acids and other agents that break down rock.

Answers

Answer: Biological weathering only refers to weathering caused by organisms -- animals, plants, fungi and microorganisms such as bacteria. While certain forms of biological weathering, such as the breaking of rock by tree roots, are sometimes categorized as either physical or chemical, biological weathering can be either physical or chemical

Explanation:

Answer:

Biological weathering can result in chemical erosion through the action of bacteria that release acids and other agents that break down rock.

Explanation:

As the bacteria colonize rocks and soils, they produce organic acids and other metabolic products that react with the minerals in the rock, causing them to break down and dissolve. Over time, this process can weaken and erode the rock, leading to chemical erosion. Additionally, the action of roots can also contribute to chemical erosion by releasing organic acids into the soil, which can further break down rock and mineral surfaces.

Explanation:

Physical changes can usually be reversed, and no new substances are created in a physical change. In a chemical change, it can’t be reversed, and there is a creation of new substances.

With this in mind:
Freezing juice is a PHYSICAL change (it can be reversed easily if the juice ice is melted, and no new substances are created)
Exploding fireworks is a CHEMICAL change (it happens due to combustion, which produces heat and light as new products, and you can’t undo the explosion of the fireworks)
Melting a chocolate bar is a PHYSICAL change (it can be reversed easily, and there are no new products as it’s the same chocolate, just as liquid)
Cutting grass is PHYSICAL (no new products are created, and whilst it can’t technically be reversed the grass will grow back, so eventually it will go back to its original state)
Rotting bananas is a CHEMICAL change (the rot creates a new substance on the bananas and it can’t be reversed)

With this logic, we can continue answering the rest.
Cutting hair is PHYSICAL
Squeezing oranges is PHYSICAL
A log burning in a fireplace is CHEMICAL
A change that does not result in a new substance is PHYSICAL
Dissolving sugar in water is PHYSICAL (this one can be tricky but it’s important to remember it can be reversed via evaporation and no new product is technically created)
Rust on an iron fence is CHEMICAL
Cake batter baked in an oven is CHEMICAL
Blue and yellow pain being mixed is PHYSICAL (while a new colour is produced and the change isn’t reversible, the change is chemical as the structure of the paint is exactly the same and no new substance is technically created)
Photosynthesis is CHEMICAL
Glass being shattered is PHYSICAL
Boiling water is PHYSICAL
Burning coal is CHEMICAL
Melting butter is PHYSICAL
Cooking eggs is CHEMICAL

Which layer of soil is generally hard and packed?

bedrock
topsoil
subsoil

Answers

Answer:

Bedrock is the layer of soil that is generally hard and packed.

C. Subsoil
Subsoil is made up of small particles that has very little living/once was living materials, which makes them hard and packed.
