The chart shows how cliamate change and rising ocean temperature might affect the types of hurricanes we see this century we see
navik [9.2K]

Answer:

Check Explanation

Explanation:

The chart to be used to answer the question is currently missing. After obtaining online, I have attached it to this solution of this question.

From the graph, the prediction shows a negative percent change in the number of category 1 and category 2 & 3 hurricanes (greater than -25% change) and category 4 & 5 hurricanes get a positive percent change of more than +75% change)

Now, taking the statements, one at a time.

A. Which type of hurricane is expected to strike more frequently this century?

From the chart, only category 4 & 5 hurricanes are predicted to have a positive percent change in number, hence, they are the ones expected to strike more frequently in this century.

B) How are hurricanes formed in the atmosphere?

This information cannot be read off from the graph. So, the answer provided isn't from this chart of prediction.

Hurricanes are formed when warm, moist air from the ocean surface begins to rise rapidly, and they encounter cooler air that forces the warm water vapor to condense& form storm clouds with drops of rain.

C) In general, will hurricanes likely become stronger or weaker this century?

The less powerful hurricanes are predicted to have more than 25% negative percent change in number.

But the most powerful categories of hurricanes are predicted to have more than 75% positive percent change in number.

Although, the true figures aren't clear, but more hurricanes that happen are bound to be classified as category 4 & 5 hurricanes. It can be perceived that hurricanes are getting stronger in this century.

D) Which areas are at the highest risk of hurricanes?

This information cannot be read off from this chart. It isn't provided.

E) Which types of hurricanes are expected to drop in frequency by more than 25% this century?

From the chart, category 1 and category 2 & 3 hurricanes are predicted to drop in frequency by more than 25% this century.

F) How many category 4 and 5 hurricanes can we expect this century?

From the chart, we're predicted to have more than 75% positive percent increase in the number of category 4 & 5 hurricanes.

The number of category 4 and 5 hurricanes we should expect this century will be more than 75% higher than the previous century.

Hope this Helps!!!

1. The following are statements about flames some of them are true while others are
hoa [83]

Answer:

i)The carbon particles are formed when the gas is not completely burnt(True)

ii)A solid or liquid must be change to gaseous state in order to make flame(TRUE)

iii)A non- luminous Bunsen flame produces has three visible regions(FALSE)

iv)The luminous Bunsen flame produces less soot than the non- luminous flame(FALSE)

v)A yellow Bunsen flame is obtained when the air holes are opened(FALSE)

vi)The luminous Bunsen flame is hotter than a non- luminous Bunsen flame(FALSE)

vii)Bunsen burner uses kerosene as a source of heat(FALSE)

Explanation:

i)When the incomplete combustion ,then CO(carbon monoxide) and C(carbon) are produced. <u>The unburnt carbon get deposited as</u><u> Soot</u>.

In complete combustion CO2(carbon dioxide) is produced.

ii)Fire, is the mixture of hot gases.Flame are result of chemical reaction between oxygen and fuel(e.g butane ,wood).Flame contain,carbon dioxide , heat ,light,steam.

iii)There are total three regions of flame in which the outer most region is the non-luminous .The non-luminous part is <u>blue(one visible region</u>) and does not emit-light.

iv) Luminous Bunsen flame produces more soot than the non- luminous flame because luminous flame contain more unburnt particles as compare to non-luminous.

luminous part has less oxygen available for complete combustion of fuel

v)When the air hole is open it means excess oxygen is supplied to the fuel.

In this case clean and luminous flame is produced.When air hole is close yellow flame is produced.

vi)Non-luminous part of flame is more hot because of complete combustion due to proper availability  of oxygen. Sometime the particle of non-luminous flame get ionize also.

vii).The bunsen burner uses Natural gas(methane) or LPG(propane and butane)as sources of heat because these are easily burnt not kerosene.

Do you<br> think a colony on Mars should be nearer the northern or southern<br> polar cap? Explain.
xxTIMURxx [149]

Answer:Hola TvT

Explanation:When the Martian polar caps were first viewed through telescopes, most scientists believed that they were made of water ice, like the polar caps on Earth. Like Earth, Mars has a North and South Pole. But while Earth's polar ice caps consist solely of water ice, Mars' polar caps are a combination of water ice and carbon dioxide ice. As the Martian seasons change, the carbon dioxide ice sublimates (vaporizes) in summer, revealing the surface, and freezes again in winter. As fall approaches, in each respective hemisphere, clouds begin to form over the polar region and the ice cap begins to grow. In spring, the polar caps recede...........Aside from ice, Mars' polar regions have some interesting geologic features. The north polar dune field is a vast concentration of sand dunes that stretches around the entire north polar cap. In some areas, the sand measures up to 500 km (300 miles) across. When the dunes begin to thaw in spring, dark spots form on their surfaces. The north polar dunes were first seen during the 1972 mapping of Mars by Mariner 9, and they are identical to dunes in Earth's desert regions..
