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.

Zircon (ZrSiO4) forms in magma as it cools into igneous rock. It is also useful for numerical dating.

b. Suggest a rule that geologists should follow when they date rocks based on the radiometric ages of crystals inside the rocks.

Answers

Answer:

Zircon is essential element in the formation of igneous ricks.

Explanation:

Zircon crystal commonly grow in rocks and are very small in size. Zircon forms magma ad the lavas as it cools and thus is useful for absolute dating but does not indicate modern age for the beach. Due to the structure of the crystal, as it solidifies in magma. Once make sure that the crystal formed inside the ricks are formed at the same time as the rock itself. As the ricks are formed in different environments just beneath the surface of the earth.

Choose the true statement about the nitrogen cycle.
a. Bacteria take nitrogen from the atmosphere and convert it into sugars.
b. Nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.
c. Nitrogen makes up about 22% of the atmosphere's composition.
d. Animals release nitrogen through urination and by dying.

Answers

The true statement about the nitrogen cycle is that: b. Nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.

Nitrogen is a chemical element with the symbol "N" and it has an atomic number of 7.

Basically, it is found in group (5) of the periodic table and as such it has 5 electrons in its outermost shell. Therefore, nitrogen has two (5) valence electrons.

Nitrogen cycle can be defined as a repeating biogeochemical process which typically involves the interconversion or circulation of nitrogen and its compounds by the actions of both living organisms and non-living things in the environment such as nitrogen fixation and decomposition. Thus, it is biogeochemical process that converts nitrogen gas into organic substances and then back to nitrogen in air.

In the real world, it is known that the leaves of plants such as peanuts, soybeans and clover contain nitrogen in a very significant amount.

In conclusion, true statement about the nitrogen cycle is that nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.

Answers

Answer:

Ghana is a West African country in Africa, along the Gulf of Guinea, just a few degrees north of the equator.

Ghana encompasses plains, low hills, rivers, Lake Volta, the world's largest artificial lake, Dodi Island and Bobowasi Island on the south Atlantic Ocean coast of Ghana.[1] Ghana can be divided into four different geographical ecoregions. The coastline is mostly a low, sandy shore backed by plains and scrub and intersected by several rivers and streams. The northern part of Ghana features high plains.[2] South-west and south-central Ghana is made up of a forested plateau region consisting of the Ashanti uplands and the Kwahu Plateau. The hilly Akwapim-Togo ranges are found along Ghana's eastern international border.[3]

The Volta Basin takes up most of south-central Ghana and Ghana's highest point is Mount Afadja which is 885 m (2,904 ft) and is found in the Akwapim-Togo ranges.[4][5] The climate is tropical and the eastern coastal belt is warm and comparatively dry, the south-west corner of Ghana is hot and humid, and the north of Ghana is warm and wet.[2] Lake Volta, the world's largest artificial lake, extends through small portions of south-eastern Ghana and many tributary rivers such as the Oti and Afram rivers flow into it.[6]

Explanation:

The northernmost part of Ghana is Pulmakong and the southernmost part of Ghana is Cape three points near Axim. Ghana lies between latitudes 4° and 12°N.[7] South Ghana contains evergreen and semi-deciduous forests consisting of trees such as mahogany, odum, ebony and it also contains much of Ghana's oil palms and mangroves with shea trees, baobabs and acacias found in the northern part of Ghana.[7]

which countries have a smaller coastline than the Philippines

Answers

All nations other than Russia, Norway, Canada, and Indonesia have a shorter coastline than the Philippines.

All countries in the world apart from Canada, Norway, Indonesia, Greenland and Russia have smaller coastlines than the Philippines.

As there are no options given, a better question to ask would be related to which countries have a longer coastline than the Philippines because of all countries in the world, the Philippians has the 6th longest coastline there is.

This is because the Philippians comprises of many islands and when the coastlines of all these islands are summed up, even the United States has less of a coastline than the Philippines even though the latter is way smaller in terms of total landmass than the former.

In being 6th on the list of longest coastlines, any country you can name apart from the 5 mentioned in the answer above, have smaller coastlines than the Philippines.

Explanation:

Answer:

A different section of the moon's face is lit up by the sun, causing it to show different phases.

Explanation:

How do the phases of the moon change?

The moon's location changes daily as it goes through its 29-day orbit. It is between the Earth and the sun at times and behind us at other times. As a result, the sun illuminates a different area of the moon's face, causing it to show different phases.

What happens to the moon's phases during the period of a month?We don't see the Moon as it moves between the Sun and the Earth because the side reflecting the Sun is facing away from the Earth. It's the new moon.So, while it appears like the Moon is changing shape over the course of a month, this is not the case. The Moon's orbit around Earth causes the phases to change.Moon Phases-

After capital flight
Now, suppose that Mexico experiences a sudden bout of political turmoil, which causes world financial markets to become uneasy. Because people now view Mexico as unstable, they decide to pull some of their assets out of Mexico and put them into more stable economies. This unexpected shock to the demand for assets in Mexico is known as capital flight.
Shift the NCO curve to illustrate the effect of capital flight. Then, on the graph representing the market for loanable funds, shift the demand curve, the supply curve, or both to reflect the change caused by the shift in NCO.
Note: You will not be graded on your final placement of the curves on the graph, but you will need to shift them correctly in order to answer the questions that follow.
Determine the equilibrium interest rate after capital flight occurs, and enter it into the second row of the table. Then determine the level of NCO that occurs along the new NCO curve at the new equilibrium interest rate.
Finally, show the effect of the change in NCO on the market for foreign exchange by shifting either the supply curve, the demand curve, or both.
