<u>Answer and Explanation:</u>

The mechanism which is responsible for moving the plates that bring change in the position of the continents is the convection in the asthenosphere.

Henry Hess, a geologist and an American Navy officer in the World War II, discovered that the sea floor and the the Mid Atlantic Ridge is spreading which helped the the scientists in studying and understanding the mechanism of how the plates move.

You could try writing flash cards with the word on one side and definition on the other or you could write the word and definition 3 times each on a piece of paper. remember not to try and cram the night before the quiz because you will lose sleep and you may not remember what you studied. (;

3. An undisturbed soil sample has the following data (Source - Lu &amp; Evett): 1. Void ratio = 0.78 2. Water content -12% 3. Sp
irga5000 [103]

Answer:

Wet unit weight = 1.94 g/cc

Dry unit weight =1.05 g/cc

density of saturation = 0.41

porosity = 0.43

Explanation:

given data

Void ratio = 0.78

Water content -12%

Specific gravity of solids - 2.68

to find out

Wet unit weight and Dry unit weight and Degree of saturation and Porosity

solution

we know that Wet unit weight formula is

Wet unit weight = \frac{Gs + e}{1+e} density of water

here Gs is specific gravity of soild and e is void ratio and density of water is 1

so Wet unit weight = \frac{2.68 + 0.78}{1+0.78}

Wet unit weight = 1.94 g/cc

and

Dry unit weight = \frac{Gs - e}{1+e} density of water

Dry unit weight = \frac{2.65 - 0.78}{1+0.78}

Dry unit weight =1.05 g/cc

and

density of saturation is

density of saturation = Wc × \frac{Gs}{e}

her Wc is water content

so density of saturation = 0.12 × \frac{2.68}{0.78}

density of saturation = 0.41

and

porosity is

porosity = \frac{e}{1+e}  

porosity =  \frac{0.78}{1+0.78}  

porosity = 0.43

. Explain the distribution (this includes DENSITY &amp; CONCENTRATION) of the world's population. Be sure to identify specific r
Kay [80]

Answer:

The concepts of population distribution and density are so closely related to ... In most countries of the world the geographic distribution of the population is not even with varying degrees of concentration of population giving rise to varying densities in the ... mainly responsible for discouraging inhabitation in certain areas.We can define population distribution as the pattern of where people live. Population distribution is

perhaps the most essential of all geographic expressions, because the ways in which people have

organized themselves in space at any given time represent the sum of all of the advances they have

made to their overall geographical area. Population distribution can also describe how people are

arranged according to different variables such as age, sex, religion, or race.

World population distribution is uneven. Sparsely-populated regions are usually harsh places to live.

These places usually have hostile environments; some examples are the Sahara Desert or Antarctica.

Densely populated areas have more habitable environments – for instance, most of Europe.

When we talk about population and its characteristics, it is easy to confuse similar concepts. For

example, you may confuse population distribution with population density. Population density is the number of people per unit of land area, whereas population distribution is the pattern of where the

people live. When you study population distribution and density at the global level, they are both

usually depicted graphically by how many people live in a square mile. When you study population at

the local or regional level, you can get a better view of patterns in where people live and how they’re

distributed. There are three basic patterns of population distribution: they can equally-spaced apart

(uniform dispersion), randomly spread out with no predictable pattern (random dispersion), or bunched

in groups (clumped dispersion).

An example of population distribution is the fact that China’s natural physical conditions resulted in

uneven population distribution. There is a huge contrast in the number of people living in eastern China

compared to the distribution in the western part of the country.

An example of population density would be that the in 2016, the population density of the United States

was 91.5 people per square mile of land area.
