What is Earth’s crust like that is located the furthest away from the center of a mid-ocean ridge? Select all that apply.

less dense
older
newer
thicker

Answers

Answer 1

Answer:

The Earth's crust that is located furthest away from the center of a mid-ocean ridge is:

Older: The farther away from the center of the mid-ocean ridge, the older the crust becomes. This is because new crust is continually formed at the ridge center and moves away in opposite directions.

Thicker: As the crust moves away from the ridge center, it cools and contracts, becoming thicker.

Less dense: The older, thicker crust is also less dense than the newly formed crust at the ridge center.

Therefore, the correct options are: older, thicker, and less dense.

Answer 2
Answer : the answer to this question is older

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.

E Astronomers measure distances to objects which are outside our solar system in light-years.Astronomers measure distances to objects which are outside our solar system in light-years.
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.

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

What type of weathering occurs to statues when they lose their features over time due to rain?

mechanical biological
chemical biological
mechanical

Answers

Answer:

Mechanical Weathering

Explanation:

Statues are typically made of rock or some other material similar to rock. Mechanical weathering is the breakdown of rocks into smaller pieces, which is why it is a type of mechanical weathering.

Answer:

The type of weathering that occurs to statues when they lose their features over time due to rain is chemical weathering.

Explanation:

Rainwater is slightly acidic due to the presence of carbon dioxide in the atmosphere, which dissolves the minerals present in the rock or stone of the statues over time. This process is known as chemical weathering, and it can cause the loss of features and details of the statue's surface. Over time, chemical weathering can completely erode a statue's features, leading to a smooth, worn surface.
