Chapter 1

Question 1

Geology Definition

Answer 1

Study of earth contents ex. rocks, minerals etc

Question 2

Environmental geology Defintion

Answer 2

Branch of geology which deals with human and earth envirment

Question 3

How Does Envirmental Geology involve in our daily lives

Answer 3

Water for drinking, washing
Soil for growing our food
Ground on which we stand
Stable? Landslides
Disaster: Floods, earthquakes

Question 4

How do we approach env geology

Answer 4

We use science of geology to solve problems resulting from interaction between five systems:

Solid earth, life, water, ice, air

Question 5

Env Geology uses many branch’s of traditional geology like:

Answer 5

Mineralogy & economic geology: minerals
Petrology: Analysis of rocks
Hydrology: study of water

Question 6

How do we study env. geology

Answer 6

It involves collection of geologic data from
-Surface(rock outcrops)
-subsurface(from boreholes)

Question 7

When did we start collection of geologic data(study of env. geology)

Answer 7

Us started in 1950’s

Question 8

Why did we start collection of geologic data(study of env. geology)
Give an example

Answer 8

Started in 1950s
Problems were observed and they needed answers
ex. Population geowth inscreaded rapdly, therefore increased demand for resocurces

Question 9

City planners(engineers) were forced to recognize geologists what?

Answer 9

recognize geologists who could produce Multi purpose maps for things like cities

Question 10

Multipurpose Maps showed areas of

Answer 10

Unstable ground
Prone to earthquakes
Highflood potential
Water of good/poor quality
Mineral resources

Question 11

How much did the government vote for multi purpose maps studies

Answer 11

Voted 184 million over four years for these studies

Question 12

Causes number one of env problems

Answer 12

1.High rate of world population Growth

Question 13

High rate of world population Growth causes env problems why?
Define carrying capacity

Answer 13

Everyone wants a good standard of life but the planet has limited supply of air, land, water , mineral resources

Carrying capacity:Idea that given amount of resources can support a limited number of people/animals/plants

Env studies have to do alot with estimating population

Question 14

Population Growth Rate (PGR) Formula

Answer 14

PGR= Birth Rate(BR)-Death Rate(DR)

Question 15

Population Doubling Time(What does it mean and Formula)

Answer 15

Time it takes for a population to double in size

PDT=70/Growth rate% in years
Rule of 70

Question 16

Theory One of Over Population(explain, its argument as well)

Answer 16

“the sky is falling”
-Earth is at or close to its carrying capacity

Many years ago one species every 25 years would go extinct but now in 1991,1700 species went extinct

Thus, earth is coming to an end and cant sustain 9-10 billion people

Argument Agaisnt
Population was not dont accurately a long time ago as it is now

Question 17

Over population Theaory Number Two

Answer 17

“Gaia Hypothesis”

Gaia (Greek goddess of the earth)
Made by James Love Lock and Lynn Margulis

Earth is a super organism whose envirmoent is controled by plants and animals that inhabit it

Question 18

Solution To Env. Problems

Answer 18

We have to plan towards a sustainable environment

Regulate food, fuel, air, water, resources for the instertst of our future generations

Question 19

What Five things to we have to regulate to solve env problems

Answer 19

1.Population Growth
2.Engery and Global warming
3.The land
4. Forests
5.other resources

Question 20

Explain Population Growth(5 Solutions for Env problem’s)

Answer 20

The Us and Europe are approaching replacement reproduction

means that babies are just reproduced to replace their parents

The population isnt decreasing or increasing

Question 21

Engery And Global Warmings(5 Solutions for Env problem’s)

Answer 21

A seripus en. problem caused by an increase in CO2 in the air
-Caused by burming of gas, coal, oil

Need to regulate

Question 22

The Land (5 Solutions for Env problem’s)

Answer 22

Number of people supported by earth is limited by amount of usuful land for arguculture
(Soil quailty is deterating)

Question 23

Forest (5 Solutions for Env problem’s)

Answer 23

Deforestiation is a big problem caused by
Clearing soil for agriculture purposes
Logging for wood
Demand for wood fuel and forest products

Question 24

Other resources (5 Solutions for Env problem’s)

Answer 24

Our society is a throwaway society
Must recycle some of our products because our products are dwindling

Mainly Paper, plastic, glass, alumin, steel
