The earliest of civilizations were based around river valleys. This allowed them to irrigate fresh water to their crops allowing for better farming and therefore, bigger and better civilizations.
<u>Answer:</u>
<em>Cleavage is the splitting of minerals along natural planes of weakness
</em>
<em></em>
<u>Explanation:</u>
There are different physical features of a mineral that are used in the identification of species of fossils. The characteristics may include hardness, Fracture, tenacity, and, cleavage. The cleavage, therefore, occurs as a result of the strengthening of the weaker bonds and the greater lattice spacing that exist in the plane. The lattice accompanies the more fragile relationship along with the place because the link cannot maintain interatomic spacing.
The property of cleavage and positioning of fracture derived from structural species of the crystals.
Producers are organisms that have the ability to manufacture their own food. Plants are producers since they make their own food using the process of photo synthesis. At the equator the mass of producers or plants is highest and this value decreases as one moves north or south of the equator. This is because the optimum conditions for plant growth exist there. therefore this means the mass of produces consumed would decrease moving from the equator to the poles.
