A moon phase cycle takes about this much time to complete.
One month
This type of plate boundary creates a mid-ocean ridge.
Divergent
Describe how energy from the sun heats up air in the atmosphere.
The energy goes to the ground first and then is transferred to the air.
What were the two roof modifications you could make in the ECC Internship?
White roofs and solar roofs.
Describe one thing humans can do to reduce our climate impact.
Use renewable energy, drive less, less livestock, trap gas underground, plant more trees, etc.
This celestial event is caused by the Moon blocking sunlight from getting to the Earth.
Solar Eclipse
What is one example of weathering?
Rain, dust storms, glacier movements, wind, ice, etc.
What causes major ocean currents to move?
Prevailing winds
Which type of plate boundary was most likely to produce an ocean-wide tsunami?
Convergent
What does the Ozone layer protect us from?
UV light from the Sun.
Name the four "spheres" that make up a planet.
Atmosphere, Biosphere, Hydrosphere and Geosphere.
What are the three main rock types?
Igneous, Sedimentary and Metamorphic
This type of pressure system will produce clouds as it allows air to rise.
Low pressure
What is Albedo a measure of?
How much light is reflected by and object.
Name three types or renewable energy sources
Hydro, Solar, Wind, Geothermal, Biomass, or Marine.
Why do we experience seasons on our planet?
The Earth is tilted. If the northern hemisphere is tilted towards the sun we experience summer. Away from the sun for winter.
The process of rock being pulled underground at a plate boundary.
Subduction
What three variables can make storms more severe?
What is a trade-off?
When you value one variable it may negatively impact others.
What is the difference between a trend and a fluctuation?
Trend - Long term change or average of data.
Fluctuation - Short term changes in data.
The key piece of evidence that proved water formed the channel on Mars.
A picture of a sample of conglomerate rock taken by the Curiosity rover.
Which two energy sources cause the rock cycle to function?
Energy for the Sun and Earth's interior.
Which two variables affect the density of water?
Temperature and salt content
What were the three criteria we considered when designed our Tsunami Alert system?
Cost, Warning Time and False Alarms
