Answer:

The largest mass extinction ever recorded on earth was that which occurred at the end of the end of the Permian period.

Explanation:

The largest mass extinction of species ever recorded on Earth, which occurred 252 million years ago and eliminated 96% of marine fauna, occurred at the end of the Permian period and was the result of global warming and left the animals of the oceans without sufficient oxygen to survive.

The lack of oxygen caused by global warming explains more than half of the loss of marine diversity in this late Permian mass extinction and other factors, such as acidification or changes in the productivity of photosynthetic organisms, acted as additional causes, according to these scientists.

The situation at the end of the Permian, when the increase of greenhouse gases in the atmosphere generated higher temperatures on Earth, is similar to the current one.

The spectrum of a blackbody has a peak wavelength of 2.80×10-7 meters. What is its temperature, in kelvins?

-BARSIC- [3]

Answer: $1.03\times 10^4K$

Explanation:

Using Weins displacement law:

$\lambda _{max}=\frac{b}{T}$

where $\lambda _{max}$ = wavelength = $2.80\times 10^{-7}m$

b = constant = $2.897\times 10^{-3}mK$

T = Temperature in Kelvin = ?

Putting the values we get:

$2.80\times 10^{-7}m=\frac{2.897\times 10^{-3}mK}{T}$

$T=1.03\times 10^4K$

Thus the temperature of the blackbody will be $1.03\times 10^4K$

Why are hurricanes so frequent in areas close to the equator? A. There is more wind near the equator. B. There is less landmass

levacccp [35]

<u>ANSWER:</u>

Hurricanes so frequent in areas close to the equator because "the ocean water can evaporate more quickly near equator".

<u>EXPLANATION:</u>

Hurricanes are fast moving wind storms that use heat and most air as their fuel. The air near the 'equator' is warm and moist causing more hurricanes.

The warm and moist air from the 'ocean surface' rises above and generates an "area of low pressure".

This causes air from nearby areas to move to the area of low pressure. This new air becomes moist and warm. This warm air when cools forms clouds.

This cloud systems and winds grows and spins fed by the "water evaporating" from the surface of the ocean. This in turn creates a storm called a hurricane.
