- INTELLECTUAL
- POLITICAL
- EMOTIONAL
- SOCIAL
It is the sum total of all the external forces, influences and conditions, which affect the life, nature, behavior and the growth, development and maturation of living organisms.
ENVIRONMENT
It is used to describe, in the aggregate, all the external forces, influences and conditions, which affect the life, nature, behavior and the growth, development and maturity of living organisms.
ENVIRONMENT
What are the 2 Greek words where the word Atmosphere came from?
- atmos - vapor or air
- sphere - ball or globe
This sustains life on the Earth and saves it from the hostile environment of outer space.
Atmosphere
It absorbs most of the cosmic rays from outer space and a major portion of the electromagnetic radiation from the sun.
Atmosphere
It transmits only here ultraviolet, visible, near-infrared radiation (300 to 2500 nanometers) and radio waves. (0.14 to 40 meters) while filtering out tissue-damaging ultraviolet waves below about 300 nanometers (nm).
Atmosphere
It comprises of 78% nitrogen, 21% oxygen, and smaller amounts of argon, carbon dioxide helium, and neon.
Atmosphere
How many percent of nitrogen does the atmosphere comprise?
78%
How many percent of oxygen does the atmosphere comprise?
21%
5 Layers of the Atmosphere (TSM ThE)
- Troposphere
- Stratosphere
- Mesosphere
- Thermosphere
- Exosphere
Reaches 12 km from the Earth’s surface
Troposphere
The thinnest layer of the atmosphere
Troposphere
Comprises roughly 80% of the weight of the atmosphere
Troposphere
This reaches 50 km from the Earth’s surface
Stratosphere
It is the part of the atmosphere where the ozone layer is located.
Stratosphere
A protective layer of O3 compounds that prevents ultraviolet radiation from directly entering the Earth’s surface
Ozone Layer
This extends between 50 km and 70 km from the Earth’s surface
Mesosphere
Coldest layer of the atmosphere
Mesosphere
Contains only 0.001% of the gases in the atmosphere
Thermosphere
Hottest layer of the atmosphere
Thermosphere
Contains the ionosphere, where aurora phenomena occur
Thermosphere
Outermost layer of the atmosphere
Exosphere
Extends as far as 6000 miles out into space
Exosphere
Hydrosphere came from the 2 Greek words; hydro and sphere. What does hydro mean?
WATER
This comprises all types of water resources oceans, seas, lakes, rivers, streams, reservoirs, polar icecaps, glaciers, and groundwater.
Hydrosphere
In nature, 97% of the earth’s water supply is in the ______.
OCEANS
About 2% of the water resources is locked in the polar __________ and ________.
Icecaps and Glaciers
Only about 1% is available as fresh surface _____________, _____________, and _____________
fit to be used for human consumption and other uses.
Water-rivers, lakes streams, groundwater
About how many % of the Earth’s surface is water-covered?
71%
The vast majority of water on the Earth’s surface is ___________________ in the oceans.
Saline Water
Litosphere came from the 2 Greek words; lithos and sphere. What does ‘lithos’ mean?
ROCK
It is the outer part of the solid earth.
Lithosphere
It is both oceanic and continental
Crust
This is about 60 miles (100 kilometers) in thickness
outermost layer of the mantle
It consists of minerals occurring in the earth’s crusts and the soil e.g. minerals, organic matter, air, and water.
Lithosphere
Biosphere came from the 2 Greek words; bios and sphere. What does ‘bios’ mean?
life or living
It indicates the realm of Iiving organisms and their interactions with the environment, via the atmosphere, hydrosphere, and lithosphere.
Biosphere
This is systematized knowledge derived from and tested by the recognition and formulation of a problem, collection of data through observation, and experimentation.
Science
It deals with the study of people and how they live together.
Social Science
It deals with the study of nature and physical world. It includes such diverse disciplines as biology, chemistry geology physics, and environmental science.
Natural Science
In its broadest sense, this encompasses all the fields of natural science.
Environmental Science
It is defined as the branch of biology focused on the study of the relationships of the natural world and the relationships between organisms and their environment.
Environmental Science
It is an interdisciplinary academic field that integrates physical, biological, and information sciences to the study of environment, and the solution of environmental problens.
Environmental Science
It is the study of living organisms and how they interact with our environment.
Environmental Science
It is a profession that applies science and mathematics to make the properties of matter and sources of energy useful in structures, machines, products, systems, and processes.
Engineering
is the application of science and engineering principles to improve the environment (air, water, and/or land resources), to provide healthful water, air, and land for human habitation and for other organisms, and to remediate polluted sites.
Environmental Engineering
It is the branch of engineering that is concerned with protecting people from the effects of adverse environmental effects, such as pollution, as well as improving environmental quality.
Environmental Engineering
It involves the planning, design, construction, and operation of equipment, systems, and structures for the benefit of society.
Environmental Engineering
It is manifested by sound engineering thought and practice.
Environmental Engineering
It is the relationships and interactions of plants and animals with the water, air, and
soil that makes up their environment.
Ecosystem
This focus on the water resource management system
Environmental Systems
This focus on the air resource management system
Environmental Systems
This focus on the solid waste management system
Environmental Systems
It is how the ecosystem is maintained in light of the major depletion of natural resources.
Sustainability
An assemblage of parts and their relationship forming a functioning entirety or whole
