What is ice wedging?

the process that transports weathered bits of rock and mineral away
the process by which water seeps into the cracks of rock and freezes, expanding the crack and causing the rock to break apart
the process by which the outer layers of rock slowly peel away due to pressure changes
the breaking down and wearing away of rock material by the movement, or action, of other rock

Answers

Answer 1

The correct answer is: the process by which water seeps into the cracks of rock and freezes, expanding the crack and causing the rock to break apart.

Ice wedging is a form of mechanical weathering in which water seeps into the cracks and joints of rocks, freezes, and expands, causing the rock to break apart. This process is particularly common in regions with frequent freeze-thaw cycles, such as in mountainous or polar regions. Over time, repeated cycles of freezing and thawing can cause rocks to disintegrate into smaller and smaller fragments, eventually producing fine sediment or soil.

Correct answer: the process by which water sweeps into the crack and causing rock to break apart.

F An astronomical unit is about 93 million kilometers.

Answers

A. The average distance between the Earth and the Sun, or A.U., is used to measure distances within our solar system.

D. Distances to things outside of our solar system are measured in terms of light-years (ly), which are the maximum distances light can travel in a year in a vacuum.

To calculate the immense distances in the cosmos, astronomers mostly employ two methods. An astronomical unit (A.U.), often known as the average distance between the Earth and the Sun, is used as a standard measurement within our solar system. One A.U. is equivalent to 150 million kilometres or 93 million miles. Within our solar system, it is used to calculate the separations between planets, asteroids, and comets. Second, astronomers use light-years to gauge distances outside of our solar system (ly). The distance that light can cover in one year in a vacuum, or 5.88 trillion miles or 9.46 trillion kilometres, is known as a light-year. We may use this method to calculate the huge separations between stars, galaxies, and other astronomical objects. As a result, astronomers employ A.U.

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
