Physical and Earth Science H (Freshman Year Midterm Review)

Energy flash cards

Kinetic energy

The energy an object has because of its motion.

Electrical energy

Energy resulting from electrical charge in particles

Thermal energy

Energy contained in a system that is responsible for tempature

Potential energy

Energy that an object has because of its position or shape

Chemical energy

Energy stared in bonds of chemical compounds

Nuclear energy

Energ. Released from the nucleus

Mechanical Energy

The energy of motion or of an object that moves

Sound energy

Energy be vibration of a object

Electromagnetic Energy

Energy that travels in waves

Eccentricity

The different orbit shapes of earth’s orbit

Circle or oval

Obliquity

The tilt of earth’s axia of rotation

Precession

The wobble of earth’s axis

23.5 degrees

Greenhouse Effect (GHE or GHG)

Infrared radiation from the sun passes through the atmosphere. It’s re-emitted in all directions be GHG molecules and clouds. To warm earth and lower the atmosphere.

Enhanced Greenhouse Effect (EGE)

Amplified warming of earth’s atmosphere. A faster way to warms the atmosphere. Caused by human activities. Leads to a increase in Carbon dioxide, methane, and nitrous oxide. Caused more heat to be trapped causing climate change.

Natural sources of greenhouse gasses

List 3 Examples

Volcanic eruptions, decomposition of organic matter, respiration from plants and animals.

Human Sources of greenhouse gasses

List 3 examples

Burning fossil fuels. transportation emissions, agricultural practices like farming livestock.

Climate Change

Long-term shifts in temperatures and weather patterns

Ways to REDUCE greenhouse gas emissions

List 3 examples

Switching to renewable energy sources, reducing transportation emissions, improving energy efficiency.

How does climate change impact wildfires?

Increase in wildfire season length, wildfire frequency, and pre burned areas

Example of potential energy converted into kinetic energy

Ball is above table and then is dropped.

Example of Electrical energy converted to kinetic energy

A electric fan

Example of chemical energy being converted into heat energy

Burning wood in a fireplace
