Great Lakes
Ecosystems
100
What type of energy do EV batteries store?
Electrical energy (chemical energy stored in the battery)
100
What does “albedo” describe?
How much light a surface reflects
100
What is the temperature like near the equator compared to the poles?
Warmer / hotter
100
This Great Lake is the largest by surface area.
Lake Superior
100
This ecosystem receives very little rainfall and has plants like cacti that store water.
The Desert
200
Name one material commonly used in EV batteriest
Lithium (also acceptable: cobalt, nickel)
200
Which reflects more sunlight: ice or asphalt?
Ice
200
The equator divides Earth into which two halves?
The Northern Hemisphere and the Southern Hemisphere
200
This Great Lake is the only one located entirely within the United States.
Lake Michigan
200
This ecosystem has lots of grass, very few trees, and is home to animals like bison and antelope.
Grassland (I will accept plains, though not all plains are grassy)
300
Why do cold temperatures affect EV battery performance?
Batteries work less efficiently in the cold
300
A surface with high albedo will absorb or reflect more sunlight?
Reflect
300
How many degrees latitude is the equator?
0° latitude 
300
This Great Lake is the shallowest and warmest of the five. It is often affected by algae blooms, due to shallowness.
Lake Erie
300
This ecosystem has permanently frozen soil beneath the surface, a short growing season, and is home to mosses, lichens, and caribou.
Tundra
400
Name one way EV batteries can be reused or recycled.
metals scrap
400
Why do darker surfaces make Earth warmer?
They absorb more sunlight and heat
400
Why do areas near the equator receive more direct sunlight?
The Sun’s rays hit the Earth more directly (less spread out)
400
This invasive species has caused major ecological damage in the Great Lakes by filtering out plankton.
zebra mussels
400
This ecosystem is found in warm areas, has dense vegetation, high rainfall, and is home to many different species.
tropical rainforest
500
How are EV batteries recycled?
Disassembly (shredding), then hydrometallurgy and pyrometallurgy
500
How can humans increase albedo in cities? Give two suggestions.
1. Light-coloured roofs, sidewalks, etc.
2. Reflective pavements with special coating
500
How many hours of daylight do areas near the equator usually have year-round?
About 12 hours
500
Two of the Great Lakes are actually considered one body of water.
Lake Michigan and Lake Huron
500
This ecosystem has cold temperatures, coniferous trees with needle-like leaves, and long winters.
Taiga (boreal forest)
