Answer 1

Answer:

salt crystallization is a type of mechanical weathering.

Explanation:

Answer 2

Answer:

Honeycomb weathering

Salt can lead to a type of weathering called honeycomb weathering. Groundwater seeps into rock cracks by capillary action and eventually evaporates. This yields salt crystals, which increase the pressure in rocks. Eventually the rocks will break down. This can leave pits of salt crystals that resemble honeycombs.

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:

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.

What is the name of the plant process that involves water vapor entering and exiting through the stomata? Responses evaporation condensation transpiration respiration

Answers

Answer:

exit of water vapour through the stomata is called transpiration

The water eventually is released to the atmosphere as vapor via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.

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

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.

It is theorized that the continents on Earth were once joined together,
forming a supercontinent called Pangaea. How long ago did Pangaea
exist? How were the continents of Africa and South America arranged in
relation to each other? Describe one piece of evidence to support their
relationship. Write your response in complete sentences

Answers

Answer:

Pangea existed many millions of years ago in many opinions, but it started back in the late Paleozoic Era until the very late Triassic. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.

Explanation:

Answer:

Pangaea is believed to have existed around 335 million years ago during the late Paleozoic and early Mesozoic eras.

During this time, the continents of Africa and South America were joined together as part of the supercontinent Pangaea. They were located in the southern hemisphere, with Africa to the east and South America to the west.

One piece of evidence to support their relationship is the similarity of plant and animal fossils found on both continents. Fossils of the ancient reptile Mesosaurus have been found in both Africa and South America, indicating that the two land masses were once connected. The distribution of fossils of other plant and animal species also suggests that Africa and South America were once part of the same landmass.

The theory of Pangaea and continental drift was first proposed by Alfred Wegener in the early 20th century, and it has since been supported by a range of geological and paleontological evidence. The movement of the continents has had a profound impact on the evolution of life on Earth, as it has created new habitats and allowed for the evolution of new species in isolation.

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

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.

Natural selection is to ensure that only the best individuals live. Natural selection does not allow the sick or the incapacitated to survive. But man does not have natural selection, only in some cases. There is also little natural selection on farms.

Answer:

Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds, evolving long necks has enabled giraffes to feed on leaves that others can't reach, giving them a competitive advantage.

A. increased competition for fewer food sources B. organisms that are less suited to changes in the environment C. easier reproduction for organisms D. a higher economic value

Answers

It is D because……………

The changes that this kind of low biodiversity would bring to an ecosystem would include increased competition for fewer food sources, organisms that are less suited to changes in the environment, and easier reproduction for organisms in A, B, and C.

What is biodiversity?

Increased competition for fewer food sources, such as with only one species of tree, means that the organisms that depend on it for food and habitat would have to compete for limited resources. This can lead to a reduction in the overall population and diversity of the organisms in the ecosystem. Low-biodiversity ecosystems are less resilient to environmental changes, such as climate change or natural disasters. With only one species of tree, the organisms in the ecosystem would be less adaptable to changes in the environment and more vulnerable to extinction.

Hence, the changes that this kind of low biodiversity would bring to an ecosystem would be increased competition for fewer food sources, organisms that are less suited to changes in the environment, and easier reproduction for organisms in A, B, and C.
