Are you looking for their name?

They are called chemotrophs; this means that they obtain their energy from chemical reactions.

They are different from phototrops, which obtain their energy from the sun, mostly through the process called photosynthesis.

Let me know if you were looking for something else than a name and if there were options:)

What are the cycles that have historically controlled natural climate variability? List the name of each cycle, its natural time

Verdich [7]

Answer:

As explained below.

Explanation:

Climate oscillation or climate cycles are a recurring oscillation within the global or regional climates and their fluctuations produce varying climatic cells and pressures often occurring on an interannual and multi annular basis.

On a decadal and millennium timescales.Current examples of the ENSO, Pacific oscillation, Antarctica, and arctic oscillation. like ENSO is characterized by flooding and drought conditions and the distribution of extreme conditions in the form of heat and cold waves.

Other cycles like the Piora oscillation, Little ice age, medieval warm period, retreating of glaciers and warming of the planet. All these cycles move on earth from the equator to tropics to temperate to polar areas and the continuous warming and cooling periods have altered the rate of spreading of the seafloor and oceanic basin.

Present warming has drastically created a major change in the evolution of species causing extinction and quick decomposition of resources. The release of carbon and methane gases over these years have raised the greenhouse effect at alarming rates.

The earth's radius at the equator is larger than that at the poles. where is the earth's surface gravity more?

TEA [102]

The gravity is more at the poles because you are closer to the core

one angle of a triangle measures 125 degrees the other two angles are in a ratio of 4:7. what are the measures of the two angles

Ilya [14]

Angles in a triangle add up to 180 degrees.
180 - 125 = 55
Add the ratios 4+7 = 11
Divide the left over angels by the ratio: 55/11 = 5
Now multiply 5 by each side of the ratio:
4:7
4*5 = 20
7*5 = 35

So the 2 angles are 20 and 35 degrees.

To check, you can add up all the angels : 20 + 35 + 125 = 180
So we know 20 and 35 is correct because it adds up to 180 degrees :)
