W.W.K We will know how the use of

energy, rocks, and minerals affect the earth

Solar Energy

Solar energy is a renewable energy resource that comes from the sun

Many other renewable energy resources such as water, and wind are replacing fossil fuels

Energy Resources

Wind Water geothermal energy Solar energy Fossil fuels Nuclear power

Fossil Fuels

We use minerals such as coal to power our various factories and cities.

The burning of fossil fuels is harmful to the atmosphere: it increases the concentration of CO2 in the air

There are 3 different types of fossil fuels which are coal, oil, and natural gas.

Minerals

We take different minerals out of the earth for various purposes

For example, we use lead, nickel, cadmium, or lithium to create batteries for our cell phones, cars, etc.

WWK: how humans impact the earth’s subsystems by methods of population growth, fossil fuel burning, and use of fresh water.

Population Growth

Studies have shown that population growth is having a huge impact on earth’s supplies and environment.Since the population of the human race is increasing rapidly, many countries are resorting to Deforestation, or the clearing of forests.Most developed economies currently consume resources much faster than they can regenerate.Due to the increase in factories to produce new goods to build cities, pollution is contaminating the air and water supply, which is killing millions of people each year. Mainly in developing countries.Because of all these problems, we are using more supplies than we are provided.

Fossil Fuels

Humans use fossil fuels to basically run all of the inventions there are today.

Fossil fuels is any combustible organic material, as oil, coal, or natural gas, derived from the remains of former life.

Burning coal, petroleum and other fossil fuels at extremely high temperatures (combustion) is the primary means by which electricity is produced, but also leads to heavy concentrations of pollutants in our air and water.

More than 2.5 million metric tons of carbon is produced by power plants

The U.S. consumes more than 20 million barrels of oil per day, with more than one million tons of coal consumed annually as well.

Fresh Water

Humans use fresh water on a daily basis basically because it is a necessity to living.

1% of the world's fresh water (~0.007% of all water on earth) is accessible for direct human uses.

This is the water found in lakes, rivers, reservoirs and those underground sources that are shallow enough to be tapped at an affordable cost.

The population is growing rapidly, putting more pressure on our water supply (demand is increasing).

The amount of water is effectively reduced by pollution and contamination (supply is decreasing).

Due to the use of fresh water in some areas, such as Florida, sinkholes, or a hole formed in soluble rock by the action of water, has caused many problems and thousands of damages to homes and cities.

Vocabulary Review Deforestation- the clearing of forests due to expansion. Fossil Fuel- any combustible organic material such as oil,

coal, or natural gas, derived from the remains of former life. Sinkhole- hole formed in soluble rock by the action of fresh

water.

Humans effect on earth

KS. What 3 things do humans use that impact earth’s

subsystems?

We will know the carbon cycle, how it exists in

the five subsystems, and how it affects life on earth.

WWK

Carbon is a nonmetallic element found mostly

in coal, petroleum, and limestone. It makes up 0.04% of the Earth’s atmosphere.

Carbon

The cyclical system in which carbon travels

through Earth’s subsystems is the carbon cycle.

The Carbon Cycle

In order to understand how carbon/carbon

dioxide exists in the subsystems, we have to know about the subsystems.

A subsystem is a part of Earth’s entire ecosystem.

The Five Subsystems and Carbon

1. Atmosphere – air 2. Biosphere – “zone of life” on earth 3. Lithosphere – outer solid part of earth

(crust) 4. Cryosphere – frozen parts of earth (glaciers,

etc.) 5. Hydrosphere – water on earth (oceans,

rivers, lakes, etc.)

The Subsystems

In the atmosphere, carbon exists in its gas

form, Carbon Dioxide. In the biosphere carbon is in its gas form in

plants and in decomposing organic things. Carbon is in its solid state in the lithosphere. It

is stored in coal and rocks like limestone. Carbon is stored in the ice of the cryosphere in

its gas form. In the hydrosphere, carbon is dissolved out of

its gas form to make HCO3, its liquid form.

Carbon in the Subsystems

Carbon affects life by providing us with fuels

such as coal, petroleum, and other fossil fuels. We also breathe it out into the air where it is

then changed into oxygen by plants.

How Carbon Affects Life

When fossil fuels like coal are burned, carbon

is sent into the atmosphere. Once there, the carbon reacts with oxygen. This forms carbon dioxide which traps the Earth’s heat in the atmosphere.

Global Warming and Carbon

How CO2 affects global warming

The contributing factors of CO2

How scientists study the relationship between CO2 and temperature.

WWK: We will know how CO2

has contributed to global

warming; moreover, we will

also know how scientists study its

history.

Svante Arrhenius

1895- Arrhenius presents his work suggesting that an increase in atmospheric CO2 levels could cause a rise in global temperature.

Many people debated this issue during the early 20th century.

Although Arrhenius supported global warming, he was more concerned about explaining what caused the ice ages.

The History and Trends of CO2

Charles David Keeling created and updated the Keeling Curve, a graph that shows the measurements of CO2 in the atmosphere at any given time since 1958.

The Mauna Loa Observatory, a climate change research facility in Hawaii, records and measures levels of CO2 in the air

Temperature and CO2

Carbon dioxide, along with other gases such as methane, nitrous oxide, and fluorinated gases, traps the sun’s radiation in the atmosphere creating the green house effect.

CO2 makes up 84% of all green house gases in the atmosphere.

The burning of fossil fuels increases the rate at which CO2 is put into the air reservoir ;therefore, the Earth’s temperature will rise.

CO2 and Global Warming

For many years, humans have significantly increased the amount of CO2 in the atmosphere through the burning of fossil fuels, materials such as coal that release carbon dioxide when used for energy.

Other natural processes like volcanic eruptions also contribute to the addition of carbon dioxide.

The Contributing factors of CO2

Scientists study the history of CO2 levels through Paleoclimatology, the study of climate prior to the widespread availability of temperature records and other data.

Scientist gather data from… Corals Fossil pollen Tree rings Ocean and lake sediments Ice cores

By analyzing ice cores, cylinders of glacier ice used to study climate change, scientists are able to estimate CO2 levels from the past.

W.W.K:The impact of changes Earth’s natural

disasters has on humans and the subsystems.

Hurricanes:• The high tides and churned- up water in a hurricane cause damage, and

sometimes deaths. • Hurricanes that stay out at sea can cause such high waves, powerful winds,

and heavy rain that even huge cargo ships can be blown off course or wrecked.

• The winds arrive first they bring lots of rain. It can collapse, causing damage to surrounding buildings as well as hurting or killing people.

• Strong winds can blow roofs off buildings, tear down trees and power lines, causing no means of communication.

• Flooding and mudslides are also problems farther inland because hurricane rains spread over such a wide area.

Earthquakes:• Earthquakes happen mainly along the “Ring Of Fire, ” an area

where the fault lines meet.• Buildings can collapse, causing damage to surrounding buildings

as well as hurting or killing people. • Building collapses are the main cause of fatalities during and after

an earthquake as the shaking ground rarely causes any deaths in and of itself.

• Major earthquakes damage structures that may lead to death while small earthquakes can barely felt.

• Earthquakes amplify the natural movements of these bodies, allowing geologists to further their understanding of the planetary layers that cannot be seen.

Tsunamis:• Tsunamis are the result of earthquakes and can be one of the

most deadly results of such a geological disturbance.• Tsunamis are large waves that are created when an earthquake

occurs out at sea. • The plates shift and the motion causes a huge wave that builds

up momentum and size as it reaches land masses.• These huge waves, as high as 100 feet can take out buildings,

structures and cause destruction for miles. • Many people have become homeless or have lost family and

friends in the furious floods of tsunamis.

Storm Surges and Floods:

• In confined harbors, the combination of storm surges, waves, and currents can also severely damage marinas and boats.

• In estuaries and bayous, salt water intrusion endangers the public health, kills vegetation.

• It can also send animals, such as snakes and alligators, fleeing from flooded areas into high places where humans are.

• Additionally, currents created by tides combine with the waves to severely erode beaches and coastal highways.

• Buildings that survive hurricane winds can be damaged if their foundations are undermined and weakened by erosion.

Volcanic Eruptions:• If the ash fall is really heavy it can make it impossible to breathe.• Volcanic ash can blanket the landscape for miles, and ash clouds can

disrupt aircraft travel.• Lava flows are almost always too slow to run over people, but they can

certainly run over houses, roads, and any other structures.• Sulfur dioxide, carbon dioxide and hydrogen are released in small amounts

up into the atmosphere cooling the Earth’s temperature.• One good effect that volcanoes have on the environment is that they

provide nutrients to the surrounding soil.

Vocabulary Review:• Ring of Fire: area where a large number of

earthquakes and volcanic eruptions occur in the basin of the Pacific ocean

• Volcanic Eruption: the sudden occurrence of a violent release of steam and volcanic material.

• Storm Surge: is produced by water being pushed toward the shore by the force of the winds moving cyclonically around the storm.
