Multiple Choice

What kind of natural resource is cotton?

• renewable

• nonrenewable

• mineral

• chemical

Multiple Choice

Which of the following is a naturally renewable resource?

• fossil fuels

• minerals

Multiple Choice

Which of the following best explains why trees are called renewable resources?

• New trees can be planted in place of trees being cut down

• Animals that depended on the tree will help the tree grow back.

• only humans use trees, so tree populations will never fall below the number that are needed.

• only paper is made from trees, so the tree pop. will never run out

Multiple Choice

Which is a source of motion energy?

• the sun

• wind

• stove

• oil

Multiple Select

• Nuclear

• Biomass (Biofuels, Wood)

• Hydroelectric

• Geothermal, Solar, and Wind

• Fossil fuels

Multiple Choice

Why are fossil fuels non-renewable?

• They take millions of years to form

• They exist in very small amounts

• They are found at the bottom of the ocean

• They are dangerous to mine and drill for

Multiple Choice

What will happen if the conservation of the natural resources of drinking water stopped?

• Water will be made by people

• More water will replace the water used

• Drinking water will eventually disappear

• People will stop needing to drink water

Multiple Choice

What is a method to generate electricity?

• Take mechanical energy from the environment through wind and water, and transform it into electrical energy

• Take chemical energy from the environment

• Take mechanical energy from the environment through rocks and plants

• Take chemical energy from the environment through clouds and rain

Multiple Choice

Which of the following best describes one way a farmer might reduce soil erosion on his farmland?

• by cleaning ground vegetation

• by increasing ground vegetation

• by avoiding fertilizer to crops

• by planting crops randomly

Multiple Choice

Maria wants to save natural resources by having a clothing drive at her school. Which clothes should the participants bring?

• Participants should bring the clothes they don't like, so they can buy new clothes from natural resources.

• Participants should bring the clothes they have worn many times and have grown out of.

• Participants should just throw those clothes away that they don't like and buy new clothes.

• Participants should just by more clothes from a factory that use a lot of electricity..

Multiple Choice

How can we conserve water in our outdoor gardens?

• Make sure the plants aren't in direct sunlight.

• We should use hot water instead of cold water, when watering plants.

• Ensure there are no leaks in the watering equipment.

• Water plants midday instead of in the morning time.

Multiple Choice

How can we use fewer trees?

• Stop using google docs and write only on paper.

• Use a glass cup instead of paper cups.

• Only use paper bags when shopping at the grocery store.

• Using paper plates instead of glass plates.

Multiple Choice

Which is not the purpose of recycling?

• to manufacture products

• to use less resources by conserving them.

• to create different resources to use

• to increase the use of resources

Greenhouse Effect and Global Warming

• Remember Carbon Dioxide is the most abundant pollutant that traps the solar radiation (heat) on Earth.

• Due to the abundance of this pollutant the temperature of earth over the last 100 years has steadily risen.

Multiple Choice

Which of the following gases affects how much radiation energy is absorbed into Earth's atmosphere.

• carbon dioxide

• argon

• nitrogen

• nitrogen dioxide

Multiple Choice

What is the direct effect of greenhouse gases?

• carbon dioxide

• global warming

• hot cars

• the ozone

Multiple Choice

What is the relationship between carbon dioxide and surface temperatures of earth's atmosphere?

• there is no relationship

• the more carbon dioxide in the atmosphere means higher surface temperatures

• the more carbon dioxide in the atmosphere means lower surface temperatures

• the less carbon dioxide in the atmosphere means higher surface temperatures

Multiple Select

What will be affected by global warming?

• a difference in precipitation

• natural disasters

• higher sea levels

• a change in precipitation patterns

Multiple Choice

Which of the following pollutants is the main cause of global warming?

• oxygen

• hydrogen sulfide

• carbon dioxide

• nitrogen

Energy Transformations

• Mechanical

• Heat/Thermal

• Chemical

• Electrical

• Nuclear

• Electromagnetic

Energy Transformations

Windmill – Mechanical (wind) 🡪 Mechanical (turning blades)

Flashlight – Chemical & Electric (batteries) 🡪 Radiant (light) & Thermal (heat)

Microwave – Electric (outlet) 🡪 Radiant (light), Mechanical (Sound) & Thermal (heat)

Firecracker – Chemical 🡪 Thermal (heat), Radiant (light), Mechanical (sound)

Bicycle – Chemical (cells in the body) 🡪 Mechanical (legs peddling) & Mechanical (bicycle)

Battery – Chemical & Electrical 🡪 nothing until it is used
