* Activity 1: What is a crime, due Monday May 2, 11:55PM
Ehab, huiyingl iang , Mohamad
a) What activities are defined as a crime?
Activities which break the social norms, and projects harm to other people or things. For example,
b) Who is a criminal?
Oxygen (O) atoms cycle through the ecosystem and the biosphere the way
other elements do (especially carbon). The Earth has a fixed supply of the
element even though it can be found everywhere, including the atmosphere,
the oceans, rocks, a
YES. IRON CYCLES TOO.
Iron (Fe) atoms also cycle through the ecosystems of the world. Although
there is cross-over, there is a difference between the cycling on land and in
the water. The differences are based on how the producers get their iron in the
While groundwater is the clean, beautiful water under our feet that can be
tapped for drinking water, there are many other sources of fresh water across
the planet. The others are not as filtered and clean. Bodies of water such as
Energy does not cycle the way nutrients and atoms do. Energy enters the
ecosystem from the Sun and exits after the organisms have taken as much as
they need. Organisms release energy back into the biosphere as heat.
Energy also enters the e
Water water everywhere and always moving around. Even the smallest water
molecule at the bottom of the ocean is moving. It just moves really slowly.
We're going to talk about the hydrologic cycle. This is the path water takes
when it moves t
There are both global and local circulations of the air around us. Scientists
have different terms for the circulation based on how large the air movements
are. They say macroscale to describe wind currents that are on a global
MAKIN' THE SOIL
The process of soil formation happens in many ways. Here are five of the
most important factors involved in soil formation. There are others, but these
are the biggies.
(1) It can be created because of the shape of the landscape. That shap
THE CARBON CYCLE
Carbon (C) is the basis of life on Earth. Scientists consider 99.9% of all
organisms on the planet to be carbon based life. Those organisms need
carbon to survive. Whether the carbon is in the form of a sugar or carbon
dioxide gas, we all
Phosphorus (P) is another one of the essential elements that cycle through
the ecosystem. It is an element that is found in the ground and then taken up
by plants and animals. Phosphorus starts its existence as phosphate ions
(PO4) in t
THE NITROGEN CYCLE
Nitrogen (N) is an element like carbon. All creatures need nitrogen to survive.
There are huge amounts of nitrogen gas in the atmosphere, but most animals
and plants have no way of using it. It needs to be fixed (put into a biologically
Once the energy from the Sun gets to Earth it begins to circulate through
different ecological systems. The energy slowly spreads out across the planet.
It moves with the water. It moves with the wind. It even moves because the
NATURAL RESOURCES AND
The Earth is a closed system. For our examples, we need to think that
nothing comes in (except energy) and nothing goes out (except energy). Even
the amount of energy that moves in and out of the Earth is equal. If more
WHERE IS GROUNDWATER?
Groundwater is water that is under the ground. Okay. You're done with the
tutorial. If you want more, you should know that groundwater is extremely
important. Civilization gets most of its water from groundwater sources. There
WE NEED THE POWER
It's just that simple. We need power. All of the time. We use one form of power
to generate electricity. We use another form of power to run our cars. We even
need power cook on the stove. Power needs are all around us but there are
Let's start with standing freshwater biomes, from a river to a lake or pond. The
water doesn't move very quickly here. It gives animals a chance to grow up.
You'll find larger fish, insects, and plants in this lake. Scientists divide lak
Two huge factors affect the global radiation balance, shortwave radiation
(coming in from the Sun) and longwave radiation (given off from the Earth).
We'll cover short wave radiation first.
THE SHORT WAVES
You already understand that radiation com
ECOLOGY - THE STUDY OF
Ecology is a science all by itself but it is also a branch of the larger sciences of
biology and geography. Ecology is the study of organisms and the
environments they live in. As an ecologist, you don't just study a fish
AN ECOLOGICAL SYSTEM
The word ecosystem is short for ecological systems. An ecosystem includes
all of the living organisms in a specific area. These systems are the plants and
animals interacting with their non-living environments (weather, Earth, Sun,
COVERING THE LITHOSPHERE
Although soil has many uses, it is really just a layer of dirt between the
atmosphere and the bedrock in the tectonic plates. The top layer of the
planet is called the lithosphere. Soil is the loose stuff on the surface of the
Biomes are unique situations. They are very
specialized ecosystems that only exist in certain
parts of the world. They are ecosystems that are
defined by their environments. Factors like
temperature, rainfall, and altitude all decide what
INTERACTIONS IN THE
Something happens between the top of the atmosphere and the surface of the
Earth. Something sucks energy (interacts with it) out of the energy sent by the
Sun. The ozone layer is a layer of the atmosphere that is about 25 ki
GROUPS WORKING AS ONE
A population is a group of organisms that are all the same species. That's it.
You're done. A group of ducks would not be a population if there were mallard
and wood ducks combined. Scientists would say that there are two
LOOK UP IN THE SKY
What is the sky? What is air? What is the atmosphere? The atmosphere is just
a thin layer of gases that surrounds the Earth. It can act many different ways
and you need it to survive. Just as there are layers inside the Earth, there are
ENERGY AROUND US
We're here to talk about the energy that interacts with the Earth. An old song
says, "Love makes the world go 'round." They were wrong. Energy makes it
all happen. Most of the Earth's energy comes from the Sun. The rest of it
comes from d
Seasonal wetlands are flooded in the winter and begin to dry out in the
summer. The moisture content of these biomes changes seasonally as
opposed to a daily cycle. Rains (and snow in colder areas) arrive in the winter
and begin to fill
A BIG BALL OF LIFE
The biosphere is all about life. Physical geographers use the
term biosphere to describe our living world. This is where all of the trees,
bugs, and animals live. The biosphere extends to the upper areas of
the atmosphere where birds an
BREAK IT DOWN
Erosion is the process that breaks things down. As far as we're concerned,
erosion is the breakdown of the continents and the land around you. The
overall effect of breaking down and weathering the land is called denudation.
Denudation is th
