Quiz 8.3 Science

An anthropogenic (human) cause of increased atmospheric carbon dioxide levels is

the burning of fossil fuel.

Greenhouse effect

Process by which atmospheric gases trap heat close to Earth's surface and prevent it from escaping into space. Naturally occurring and necessary for life to exist.

Climate Change

a change in Earth's climate. This could be a change in Earth's usual temperature. Or it could be a change in where rain and snow usually fall on Earth.

Greenhouse gases

Gases in the atmosphere that trap heat energy.

Renewable energy

Any source of energy that can be continually produced and is inexhaustible given current conditions.

Fossil fuel

a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms. Non-Renewable

Energy from the Sun reaches the Earth

by radiation

Which of the following absorb carbon dioxide gas?

Plants

If human civilization had never developed on Earth, would there be a greenhouse effect?

Yes, the greenhouse effect is caused by naturally occurring gases.

Gases in the atmosphere which are involved in the greenhouse effect are _____?

carbon dioxide,methane,nitrous oxide

Which is an effect of climate change?

All of these

A layer of gas around a planet

atmosphere

Objects with low albedos

are highly absorbent and tend to have higher temperatures

Objects high in albedo tend to be

natural and light in color

Objects with high albedo

are highly reflective, and tend to have cooler temperatures

An object that is good at reflecting energy is said to have a

high albedo

As cities grow larger, what happens to the average temperature of the city…

Temperature increases due to lower albedo

Carbon

An element that is in all living things, or things that were once living.

solar power

the Sun's energy is collected and converted to useable energy; a renewable resource

wind power

turbines harness the movement of air and convert it to useable energy; a renewable resource

geothermal

heat is harnessed from deep beneath Earth's surface and converted to useable energy; a renewable resource

nonrenewable resource

an energy resource that takes millions of years to form from the remains of plants and animals such as coal, oil, and natural gas

Biomass

Fuel source from biological products (corn, wood, manure)

Where must Tidal Energy be located

On the ocean

hydropower

electricity generation using the power of falling water DAM POWER

What does geo mean?

Earth

what are the benefits of geothermal energy?

its clean and available 24 hours a day.

Nuclear

Non-renewable energy source created by splitting uranium to produce heat.

Biomass

Energy source that uses energy from organic matter (living things) to produce steam to spin a turbine when burnt. (Renewable)

turbine

A device which blades are turned by a force (that of wind, water, or steam).

What gives geothermal energy its power?

Heat generated inside the Earth

Dams built to regulate the flow of water are important to which type of alternative energy resource?

Hydroelectricity

Which of these could be used for biomass energy?

wood

The main renewable resources are:

Solar, wind, biomass, geothermal, hydroelectric

These are disadvantages of what energy? Not available in all places, harmful gases can come out of the ground, expensive to build power plants, not easy to transport

Geothermal

Choose one disadvantage to renewable energy.

expensive to build the part that is going to trap the energy

What energy has these disadvantages? Need to have rain, building a dam can damage the environment.

Hydroelectric

These are disadvantages of what energy? Not available at night, expensive, panels are inefficient.

Solar

photovoltaic (PV) cells

Device that converts radiant (solar) energy directly into electrical energy. Also called a solar cell.

fuel cell

a device that uses hydrogen gas as a fuel to produce electricity
