100
This is the zone that refers to the perfect distance from a star so that it allows for a temperature that is not too hot and not too cold. 

Goldilocks Zone

100

This is the term for very low gravity.

microgravity

100

This was invented so astronauts could do space walks and maintenance on the space station. 

spacesuit

100

This is the amount of work being done if a man pushes on the wall with 200N of force but it does not move. 

no work is being done

100

Fertilizer from a field can runoff into a nearby river and do this.

pollute it

200

This is another name for the Goldilocks Zone

habitable zone or inhabitable zone

200

Since there is very low gravity in space, astronauts' muscles and bones do this.

become weak or atrophy

200

Equipment used in the space station must be attached with these so they are not floating around due to microgravity.

cords

200

This is the unit of measurement for work.

Joules

200

Storm surges and flooding are most commonly caused by this natural disaster.

hurricanes

300

Because Earth is the perfect distance from the Sun it allows for life to have access to this, while inner planets have boiling water and outer planets have ice. 

liquid water

300

These were the name of the missions to put a man on the moon. 

Apollo

300

Because there is no oxygen for astronauts to breathe in space they must have these attached to their spacesuits when outside the space station. 

backpack with oxygen canisters

300

This is the unit of measurement for force and distance.

Newtons and meters 

300

This the term used to define the different amount of species in an environment.

biodiversity

400

The inner core of Earth is made of iron which creates this that protects us from the Sun's radioactive solar particles. 

magnetic field

400

The Apollo missions had to orbit the Earth and use its force of this to accelerate towards the Moon.

gravity

400
This helps prevent astronauts from muscles and bone atrophy.

exercising daily

400
This is the amount of work done if a box is pushed with a force of 10 N across a distance of 3 m.

30 J

400
When biodiversity increases it does this to stability and makes it more likely for an environment to recover from a disaster. 

increases

500

The composition of Earth's atmosphere is mostly made of nitrogen and this other element which creates the ozone layer. 

oxygen

500

Without the Earth's atmosphere plants and animals would not be able to exchange this. 

gases or carbon dioxide and oxygen

500

Insulated layers in spacesuits are necessary because space varies in this. 

extreme temperatures

500
These allow for work to be done easier because they decrease the force and increase the distance an object moves. 

simple machines

500

Primary succession occurs after disasters leave bare rock in an environment this type of succession occurs after a disaster, such as a hurricane, leaves soil.
