What process do plants use to make their own food?
Photosynthesis
What is a biotic factor?
A living part of the environment (e.g., animals, plants)
Name 3 types of structure.
Frame, Shell, Solid
What is conduction?
Heat transfer through direct contact
What is the epicentre of an earthquake?
The point on Earth’s surface directly above the earthquake focus
What part of the plant carries out photosynthesis?
Leaves
What is mutualism?
A relationship where both species benefit
What is tension?
What is the difference between passive and active heating?
Passive uses sunlight/design; active uses machines or technology
Name one type of weathering.
Physical, Biological, or Chemical
What is the chemical equation for cellular respiration?
Glucose + oxygen → carbon dioxide + water + energy
What is a primary consumer?
An animal that eats producers (plants)
What is the difference between dynamic and static load? Use an example to show your knowledge.
Static load refers to the weight of the structure itself (dead load) and the weight of occupants when stationary (live load), while dynamic load refers to the forces generated by movement on the stairs, such as walking, running, or jumping
How do molecules move in cold air vs hot air?
Cold = molecules move slowly
Hot = move quickly
What kind of rock cools quickly outside the Earth?
Extrusive igneous rock
What is transpiration, and why is it important?

What do tectonic plates do at a divergent boundary?
Move apart
What is the difference between osmosis and diffusion?
Osmosis is the movement of water through a membrane; diffusion is the movement of particles from high to low concentration
What is the difference between primary and secondary succession?
Primary succession happens in a lifeless area; secondary happens after disturbance in an existing ecosystem
Name all three internal force types.
Tension, Compression, Shear
What are the three methods of heat transfer?
Conduction, Convection, Radiation
