Answer: The 4 layers that make up the earth is the crust, mantle, inner core and outer core.

Explanation: The crust, which is a main layer is where we live on. Without the crust, we'll be standing on the mantle! The temperate of the crust is 392 Fahrenheit! The crust is 30 km thick. The mantle is the second layer of the earth. It's below the crust and it's hot, dense and semi-solid. It's mostly made of iron, magnesium and silicon. It can reach as hot as 1000 Celsius (1832 Fahrenheit)! It's about 2900 km thick! Anyone who standing on it will melt! The inner core is the 3rd layer. It's below the mantle and made out of liquid iron (molten iron) and nickel. It is about 5,200 Celsius (9392 Fahrenheit). Now that is hot! Hotter than a fire even a heater! The last layer is the outer core. It's made out of liquid iron and nickel, like the inner core. The outer core can be as hot as 5500 Celsius (8132 to 9932 Fahrenheit!)

These ecological levels of organization are ranked in ascending order as follows: D. individual → population→ community→ ecosystem.

An ecosystem can be defined as a biological community that is typically made up of living organisms (biotic factors) such as individuals and the physical environment (abiotic factors) in which they interact.

Basically, the individual organisms in an ecosystem forms a population and this also gives rise to a community. This ultimately implies that, the ecological levels of organization are ranked in ascending order as follows:

Answer:preventing or reducing pollution from the land and from streams

Explanation: This is true because these said streams and other bodies of water can flow into the ocean

The key to protecting the oceans is preventing or reducing pollution from the land and from streams is reducing population growth along the coastline. The correct option is A.

Pollution is the release of potentially harmful substances into the environment. These potentially damaging compounds are referred to as pollutants.

Despite the fact that metropolitan areas are often more polluted than the countryside, pollution can nonetheless migrate to isolated locations where no one lives.

For instance, it has been demonstrated that the Antarctic ice sheet contains chemicals and pesticides. The Northern Pacific Ocean's Great Pacific Garbage Patch is a vast collection of little plastic waste.

Therefore, the correct option is A, reducing population growth along the coastline.

Answer:

Water as a constructive force: It is involved in the deposition of sediments. It transports rock fragments, soil, and other debris at a particular area. This process eventually causes them to accumulate and form land features. Water as a destructive force: It is involved in weathering and erosion.

Explanation:

(pls mark brainliest if u can)

:)

Water can be both a destructive and a constructive force.

• The forces, which form or create an existing landform are known as the constructive forces. While the force, which tears or lowers down the surface features of the Earth are known as the destructive forces.

• Water can be considered as the constructive force as it carries sediment down the river and with the river becoming shallow, the deposition of the sediments takes place giving rise to landforms called deltas.

• On the other hand, water can also be considered as a destructive force as it takes part in processes like erosion and weathering. It breaks down and wears away the rocks and land masses.

Thus, water can be both destructive and constructive.

Answer:

The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. ... This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.

Advantage: helps in finding the exact ph value with a narrower range.

Disadvantage: You don't know the exact ph value on a regular scale.

Explanation:

The pH paper is a pH paper with a color indicator that helps in determining the pH value precisely between the 4.5 to 7.5 pH range. It is accurate in comparison to other pH papers such as 0-14 paper. One no need to guess the color between the different colors from various color mixtures as it has a more precise color reading that helps in finding accurate pH value in a narrow range.

On a regular scale, it is not as accurate and one can not find the exact value as it provides a narrow range value between 4.5 to 7.5.

The theory behind the formation of helium and gold is the fusing of hydrogen nuclei results in the formation of a light element like helium. One proton makes up the hydrogen nucleus. New helium atoms are created when protons combine. When helium atoms combine through enough consecutive collisions, as occurs during a supernova, they combine to generate heavier metals like gold. The correct option is 4.

What is fusion?

Fusion is a process in which two nuclei combine to form a large, heavier nucleus. This is a nuclear reaction. Nuclear reactions are of two types, fission, and fusion.

Smaller element or lighter elements like hydrogen and helium are formed by the process of nuclear fission, in which the division of element occur from smaller nuclei.

Heavier elements are formed by the process of nuclear fusion. Where lighter elements joined to create heavier elements.

Thus, the correct option is 4.

C. Is travelling on a curve in the road.

Explanation:  the two vehicles behind the truck is moving at a constant speed because there is no change in velocity. The truck is changing directions AND speed (Acceleration/Velocity).

The  pickup truck has a changing velocity because the pickup truck- truck is travelling on a curve in the road.

Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. 60 km/h northbound).

Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity; both magnitude and direction are needed to define it.

The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1).

Therefore, The  pickup truck has a changing velocity because the pickup truck- truck is travelling on a curve in the road.

Answer:

All living organism need some method of moving substances from one part of the body to other parts of the body. For example, in living organisms food and oxygen are moved in the body to all the cells and waste materials such as carbon dioxide is taken away from them. The system of moving substances in different parts of body is called transport system. In plants, food and water are transported by bundles of tubes present in stem called phloem and xylem. In animals, food, water and respiratory gases (oxygen and carbon dioxide) and other substances are transported by blood.

In plants, transport system is not complicated as in animals. The transport system in plants consists of bundles of tubes in the stem, branches and roots. These tubes are called xylem and phloem. The main function of xylem is to transport water and dissolved minerals from the roots to rest of the plant body. While, the phloem transports the food manufactured in the leaves to all parts of the plant.

Bacteria and Plants use the process of chemosynthesis to create/make food using chemical reactions.

Explanation:

"Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen. ... Bacteria that live in the deep ocean, near hydrothermal vents, also produce food through chemosynthesis."
