<span>An eon is a geologically around tens of millions of years. A period is a million year included in an eon which is also made up of several eras. Therefore my answer is a period due to it being a subset of an era which is a subset of an eon.</span>
Answer:
Environmental
Explanation:
if you think about it all things lead back to the Environment
Answer:
True
Explanation:
If a major earthquake occurs on one side of a planet and there is a seismic recording station on the opposite side of the planet, then the seismic P and S waves that generates due to the earthquake wont reach the station on the other side because earth's core is comprised of two parts, where the other core is liquid and the inner core is solid in nature.
As waves propagates through the interior of the earth, it then reaches on the core mantle boundary, where the P waves gets refracted and further flows through the outer liquid, depending upon its intensity. But the S waves are slow and cannot travel in liquid, so it gets absorbed at that core-mantle boundary.
<u><em>As the waves propagates through the earth's interior, its intensity and speed decreases with the increasing distance as well as depth</em></u>. This is the reason why the waves does not reach the station on the other side.
Therefore, <u>the above given statement is true</u>.

Heron’s formula: Area Use the triangle pictured to calculate the following measurements. Perimeter: p = units Semiperimeter: s = units Area: A ≈ square units. The triangle is 8 by 12 by 10
Part a) Calculate the Perimeter:
The perimeter of the triangle is the sum of its sides.
the answer Part a) is
The perimeter is equal to 
Part b) Calculate the Semi-perimeter:
The semiperimeter of a polygon is half its perimeter.
the answer part b) is
the semiperimeter is equal to 
Part c) Calculate the Area
we know that
You can calculate the area of a triangle if you know the lengths of all three sides, using a formula that
It is called "Heron's Formula"
where
s: is the semi-perimeter
a, b, c are the length sides.
the answer Part c) is
