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

When the oxygen in the air combines with the iron exposed by paint peeling off an old
bicycle, a new, red-colored, crumbly substance is formed.

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.

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.

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.

Answer:

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.

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.

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.

Answer:

salt crystallization is a type of mechanical weathering.

Explanation:

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.

Each university team belongs to only one conference (e.g., the University of Houston belongs to American Athletic Conference; the University of Mississippi belongs to the Southeastern Conference, etc.); but a few teams may not belong to any conference. A conference has several teams; no conference has fewer than six (6) teams. Each team can have a maximum of twenty (20) players and a minimum of twelve (12) players. Each player can play for only one team. Each team has from three (3) to seven (7) coaches on its coaching staff and a coach works for only one team. Lots of games are played in each university location every year; but a game between any two universities is played at a given location only one time a year. Three referees from a larger pool of referees are assigned to each game. A referee can work several games; however, some referees may not be assigned to any game. Players may play in several games, but it is possible that some players simply sit on the bench and do not play in any game. A game involves at least ten players. Player performance statistics (i.e., points scored, rebounds, assists, minutes played, and personal fouls committed) are recorded for each player for every game. Information collected about a game includes the final score, the attendance, and the date of the game. During the summer months, some of the players serve as counselors in summer youth basketball camps. These camps are identified by their unique campsite location (e.g., Mason, Bellaire, Kenwood, etc.). Each camp has at least three (3) players who serve as counselors. A player may work in a number of camps. A player can be identified by student number only. The other attributes for a player include name, major, number of credit hours completed, and grade point average. For a coach, relevant attributes include name, title (e.g., head coach, assistant coach), salary, address, and telephone number. Attributes for a referee include name, salary, years of experience, address, telephone number, and certifications. Both coaches and referees are identified by their personal NCAA identification number. A team is identified by the name of the university. Other team attributes include current ranking, capacity of home court, and number of players. Each conference has a unique name, number of teams, and an annual budget. For the basketball camps, data is available on the campsite (i.e., location) and the number of courts. When a referee retires, all links to the games handled by that referee should be removed. Likewise, if a game is cancelled, all links to the referees for that game should be removed. Although it is does not happen often, a university may sometimes leave the conference of which it is a member. Naturally, we want to keep the team in the database since the university could decide to join another conference at a later date. However, if a team (university) leaves the NCAA altogether, all players and coaches of that team should be removed from the database along with the team. In all other relationships that exist in the database, the default value of "Restriction of Deletion" should be explicitly indicated.1.
