Unit 1
We have different types of media and communication systems because...
There are different audiences with different resources receiving the communication.
Name and describe the 3 types of relationships among organisms...
What is...
Predation: one organism kills and
eats another organism
Competition: two organisms fight
over resources
Symbiosis: two organisms have a
close relationship that benefits
at least one of them
Describe a divergent plate boundary.
What is...
A divergent plate boundary is where 2 plates spread apart
The role of the Sun in the water cycle.
What is to evaporate water and start the water cycle?
The place where 2 tectonic plates meet.
What is a tectonic plate boundary?
A suspension bridge has a lot of forces acting on it.
The force acting on the cables is...
The force acting on the columns is...
Explain how you know
What is...
Tension is acting on the cables because they are stretching
Compression is acting on the columns because they are squeezed.
Where does energy begin in an ecosystem? Explain why.
What is...
Energy begins with the Sun because the Sun gives energy to producers to make their own food
Describe a subduction zone.
What is...
A subduction zone is where 1 plate goes under another
The role of gravity in the water cycle.
What is to force water to move downward, causing precipitation and runoff
One thing scientist can predict about earthquakes.
What is the location of earthquakes?
Define the 4 main components of the universal system model.
What is...
Input: what goes into the system
Process: what happens to the inputs
Output: what comes out of the system.
Feedback: the information about how the system is working?
Describe how each of the 3 types of organisms get their energy
Producers
Consumers
Decomposers
What is...
Producers make their own energy through photosynthesis (ex. plants)
Consumers get their energy by eating other organisms.
3. Decomposers get their energy from breaking down dead plants and animals
Describe a transform plate boundary
What is...
A transform plate boundary is where 2 plates slide past each other.
Water falling from the sky.
What is precipitation?
Rocks being displaced by wind, air, gravity, or glaciers
What is erosion?
Explain what each of the following subsystems does:
Suspension
Guidance
Propulsion
Structure
Control
Support
What is...
Suspension-supports the weight of a vehicle
Guidance-helps the vehicle stay on course
Propulsion-moves the vehicle forward
Structure-holds the vehicle up
Control-controls speed and direction
Support-helps the vehicle but not a part of it
Describe each of the forms of symbiotic relationships
Mutualism
Commensalism
Parasitism
What is...
Mutualism: Both organisms helped
Commensalism: 1 organism helped, 1 not affected
3. Parasitism: 1 organism helped, 1 harmed
Describe a convergent plate boundary.
What is...
A convergent plate boundary is where 2 plates push together (collide)
Animal released in the waste of animals.
What is excretion?
Smaller pieces of rocks.
What is sediments?
The 5 parts of a communication system and their jobs.
What is...
Source - creates the original message/information to be communicated
Encoder- changes the message into an electrical signal so it can be sent
Transmitter- sends the electrical signal
Receiver- captures the electrical signal
5. Decoder- changes the electrical signal back to an understandable message
The difference between photosynthesis and cellular respiration.
What is...
In photosynthesis plants make their own food (sugar) and release oxygen using water, carbon dioxide and sunlight.
In cellular respiration, organisms use oxygen to break down sugar into energy for their cells, releasing carbon dioxide.
These landforms are created at
Convergent boundary
Divergent boundary
Subduction zone.
What is ...
Mountains?
Rift valleys?
Volcanoes?
The water cycle is...
What is
The continuous process of water moving around the planet between land, oceans, and air?
The steps of the water cycle.
What is
Evaporation
Condensation
Precipitation
Runoff water
Infiltration
Transpiration
Groundwater storage
Excretion
