What would have to happen for an ice cube to turn into water, and then to water vapor? 

There are 2 processes, name both of them

Melting 

Evaporating 

Both require heat

What is kinetic energy

Energy that an object in motion has 

100

What is the difference between weather and climate?

Weather is daily, while climate is long term

What are the 3 types of rocks? 

Igneous

Metamorphic 

Sedimentary 

200

How could you separate out salt from water? 

Boil the mixture until all of the water evaporates 

200

What is electrical energy

Energy from the flow of electrons 

200

In a convection current, one kind of air (rises/sinks) and the other kind of air (rises/sinks) creating a current. This creates zones of pressure that cause weather. 

Hot air - rises 

Cold air - sinks 

200

How do plants get their "food" 

They make sugar using the energy from sunlight, water, and carbon dioxide from the air 

200

For a sedimentary rock to become an igneous rock, what would need to happen? 

A sedimentary rock would have to break down, and then the pieces would need to be trapped beneath the Earth to be heated up, come out of a volcano, and then cool 

300

Aluminum has a density of 2.7g/cm^3. Will it float or sink in water? 

Sink, anything with a density above 1g/cm^3 will sink 

300

Which has more potential energy, something 10ft off the ground or something 20ft off the ground AND Why? 

20 ft off the ground because things that are up higher have more potential energy

300

What is it called when water vapor cools and turns back in to liquid water? 

Condensation

Give an example of a producer and a consumer in an ecosystem 

Producer - any plant 

Consumer - anything that eats plants 

300
Give one piece of evidence for the theory of tectonic plates, that Earth's crust is divided into several different pieces 

- Fossils of the same plants are found on different continents and can be dated to the same time 

- Continents moving away/ closer to each other 

- Seafloor spreading 

- The continents appear to fit together

To increase the gravity between 2 things, what can you do - there are 2 options you need to list both

Increase the mass of the objects or decrease the distance between the objects

Where is most of the world's water located AND how much of the world's water is freshwater? 


In oceans, and only about 3% is freshwater 

400

What is an animal's niche? 

Where they live and what they eat 

400

What causes Earthquakes? 

Two plats sliding against each other, and they get stuck. When they are finally released the build-up pressure causes an earthquake. 

500

Which will be good conductors of heat and electricity, metals or nonmetals? 

Give an example of an element that conducts electricity. 

Metals, 

Copper, Iron, Silver, Gold, Lead, Nickel, etc. 

500

What kind of energy travels in waves? 

Double points if you can identify what color has the longest wavelength

Electromagnetic (light) energy 

Violet has the longest wavelength 

500

What causes the seasons? There are TWO things you need to say

The Earth's revolution around the sun and the Earth's tilt 

500

In a food web, eagles eat salmon. What would happen if the river where the salmon live got polluted? 

- Would the number of salmon increase or decrease?

- Would the number of eagles increase or decrease? 

Both salmon and eagles would decrease

What is the difference between renewable and non-renewable resources? Give an example of each 

Renewable resources can be replenished - like trees 

Non-renewable resources cannot be replenished - like metals that we use for electronics
