Which of the following scenarios are examples of positive-feedback mechanism? Check all that are correct

Answers

Answer 1

Answer: Deforestation near the Sahara Desert causes the soil to be exposed. Exposed soil evaporates moisture more readily. Insufficient moisture leads to the death of trees.

A warmer atmosphere causes more evaporation. Water vapor is a greenhouse gas, so this increases the temperature.

Warmer temperatures cause snow to melt. This makes the ground darker, allowing more solar radiation to be absorbed. The warmer ground warms the atmosphere.

Explanation:

Positive feedback mechanism refers to, the changes in a system, which induces further changes. It exists in an environment that leads to the rise in the causative effect of the environment which can change the precipitation, temperature, precipitation and other climatic conditions of the area

Therefore, the examples of positive-feedback mechanism include:

• Deforestation near the Sahara Desert causes the soil to be exposed. Exposed soil evaporates moisture more readily. Insufficient moisture leads to the death of trees.

• A warmer atmosphere causes more evaporation. Water vapor is a greenhouse gas, so this increases the temperature.

• Warmer temperatures cause snow to melt. This makes the ground darker, allowing more solar radiation to be absorbed. The warmer ground warms the atmosphere.

Resources are required on other to ensure that an organization functions well as it will be impossible to produce without the needed help (resources). Similarly, it will be impossible to survive without the availability of nature resources as they help us breath, make money, in food production and so on.

Resources conservation involves the effective and efficient use of resources. Conservation of resources can be enhanced in ways such as :

Embracing the use of renewables : The use of renewable energy sources provides a clean choice of energy which is obtained from nature's routine. The use of solar energy frolic the sun or wind powered energy obtained from natural breeze or wind.

Embrace Recycling : Recycling involves the reuse of already used materials as a form of raw material to make new products, these ensures that optimum use of the resources at our disposal is achieved while also ensuring that we have a cleaner environment.

Use of reusable goods or materials : The large influx of onr-tine use products such as disposables and certain plastic materials has contributed to large quantities of water materials on landfills, they adoption of reusable materials which can be used over certain period of time will go a long way in controlling these waste Influx.

Which processes bring about changes in the temperature and/or salinity of surface waters?

Answers

However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.

"Why Do We Study the Sun?" How does the Sun help to protect life on Earth?

Answers

Answer:

We study about the sun because  

The sun is a normal star. It is much closer to us than any other star, and by studying the sun, we can therefore learn more about other stars. The better we understand other stars, the more we know about the Milky Way. From there we know more about other galaxies and in the end we learn more about the universe.

Explanation:

How does the Sun help to protect life on Earth?

It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.

Briefly explain why there was a split in Islam that resulted in the creation of the two different sects.

Answers

Answer: It is not realy a "split". That would imply two relatively large groups. The fact is that at least 85% of those who call themselves Muslim are all from one group. They are the people who follow the Qur'an and the example of Prophet Muhammad (peace be upon him). They are called 'sunni' Muslims, by some people. In fact, they are simply true Muslims.

The other 15% are all deviant sects that have corrupted the true, original teachings. Anyone who studies Islam can see how the other groups have changed the original message.

Shiites, Ahmadiyyah, Alawi, Ismaili, Druze are some names of deviant groups.

In fact, Muhammad said that there would be such deviants; and he condemned their teachings as leading away from God. He said that the only rightly-guided group would be the one that stuck to the Qur'an and to his example. We thank God that it is the clear majority.

For an understanding of why the Shiite sect developed, you can go to Wikipedia for a detailed explanation. For examples of how they have gone astray from the healthy and true religion, you can go to You Tube and search: Real Shiah Faces.

a. No fronts associated with storm
b. A warm-core of low pressure
c. Isobars are more course and less circular
d. Smaller in area
e. Storm weakens with height
f. A cold core
g. Storm intensifies with height

Answers

Answer:

a. Tropical cyclone

b. Tropical cyclone

c. Tropical cyclone

d. Tropical cyclones

e. Mid latitude cyclone

f. Mid latitude cyclone

g. Tropical cyclone

Explanation:

Tropical cyclone is rapidly rotating storm which destroys everything that comes in its way. It intensifies with height and usually covers smaller area.

Mid latitude cyclone is most strong form of cyclone which forms due to temperature difference, Warn air at cold front rises and create a low pressure which gives rise to cyclone.

Ocean life appears to be affected by a relatively small number of variables such as temperature, density, available sunlight, available nutrients. If any one of these variables changes how do you think it might it impact the human food web?

Answers

Answer:

A change in one of these variables can cause a population decrease in some living being that has the ocean as its habitat. This decrease would affect the feeding of animals that consume this living being and this will disharmonize the entire food chain of consumers above this living being.

Explanation:

Although the ocean is affected by a relatively small number of variables. These variables are essential for the maintenance of living beings within the ocean. If one of these variables is modified, in the long term, many species of living beings can be negatively impacted in an intense way, even having their survival in danger and decreasing their population density. This would be very harmful to the harmony of food chains within the ocean. That's because, as you may already know, the food chain is a feeding sequence between living beings, where one species feeds on another, which shows how one species depends on the other to survive.

Thus, if there is a change in the variables that act on the ocean and this change causes the population reduction of a species of living being. The species of animals that feed on this living being will also be affected as they will not have enough food to sustain themselves. Isss will decrease the population density of this second species, affecting the species that will feed on it, and so on.

Temperate Forests ⇒ Trees that lose leaves in fall

Here trees change their behavior every season to survive the cold. Their most distinguishing feature is how their leaves change color in response to the season and in the fall, they shed their leaves.

Boreal Forests ⇒ Evergreen

Boreal forests are the largest forest areas in the world. Areas tey cover are in Canada, Russia and Alaska and on account of being able to survive the cold weather, they are evergreen.

Rain Forest ⇒ Giant Vines

Rain forests have a lot of canopy like trees which blocks sunlight for other plants. These plants respond by using large vines to reach sunlight.

Chaparral ⇒ Grasses and Shrubs

These have the shortest and least numerous trees of the bunch. There are also a lot of grasses and shrubs. You will find these in the California.
