Energy, Waves and Information Transfer Unit (EWIT)
What type of energy is in a battery.
Chemical energy
If a snake eats a rabbit and suddenly the snake population starts to decline, what might happen to the rabbit population?
The rabbit population will increase because now they have no predators hunting them.
What happens when 2 plates meet at a transform boundary?
The plates will rub against each other, and depending on the pressure they will cause an earthquake.
What is H2O?
H2O = Water
Which resistor lets more current through a circuit? A 20 Ohm resistor or a 60 Ohm resistor.
A 20 Ohm resistor
Where do carnivores get their food from?
A - By eating other animals
B - From the sun
C - From plants
Correct Answer - C
What happens at a convergent boundary and a divergent boundary?
At a convergent boundary, the plates move closer together, but at a divergent boundary, they move farther apart.
Name the 3 plate boundaries.
Convergent, Divergent, and Transform.
Is more current flowing through a thin wire or a thick wire.
A thick wire
Name a Biotic & Biotic interaction.
Answers vary - Human walking a dog, Rabbit eating plants.
Why does subduction happen at a convergent boundary?
Because when the 2 pieces collide, the less dense crust goes under the more dense crust.
Name a natural disaster
Answers vary: Tornado, Hurricane, Earthquake, Tsunami, Dust Storm, Flood.
I have a circuit with 2 light bulbs, and my cousin has one with 6 light bulbs. Whose circuit will have the dimmer light bulbs.
My cousin's will have the dimmer bulbs
What does the secondary consumer eat?
The primary consumer
Why does California get so many earthquakes?
Because the San Andreas fault line is running along the coast, and fault lines cause a place to get a lot of earthquakes.
What does a tertiary consumer eat?
It eats a secondary consumer
My sister has a light bulb that is too bright. How can she fix her problem?
She can add a resistor to her circuit.
Grass - rabbit - snake - eagle
What would happen to the ecosystem if the eagle population declines?
The snake population would increase and they would eat all the rabbit population, which would lead the rabbit population to decrease. Then eventually, the snake population will decrease.
Name one thing that happens at a divergent boundary?
Earthquakes, Seafloor spreading, Volcanic eruptions, etc.
What eats an apex predator?
Nothing. The apex predator is at the top of the food chain.
