<u>Answer:
</u>
The build-up of three oxygen created our ozone layer around two billion years ago.
<u>Explanation:
</u>
- The ozone layer is a part of the stratosphere which is located right after the troposphere in the atmosphere of the Earth.
- The ozone gas is made up of the abundance of three oxygen molecules combining with the ultraviolet radiation emitted by the Sun.
- The development of the ozone layer happened around two billion years ago when the oxygen concentration levels on the planet began to rise slowly and gradually.
Agriculture availibilty is profound in these areas as fields for agriculture is great for farmers. Spices and vegetables can be grown very well.
Answer:
Yes, if we take the square roots of 25, 144 and 169 (5, 12, 13)
Not by using those measures as is (sides of a triangle with 25, 144 and 169).
Explanation:
A right triangle is a triangle with an angle of 90 degrees, and the side facing that angle of 90 degrees is called an hypotenuse.
The hypotenuse measurement squared is equal to the squared measurements of the other two sides:
c² = a² + b²
And those squares do verify the equation:
169 = 144 + 25
So, that's a rectangle (right) triangle, with sides measuring 5, 12 and 13.
