Particle Theory of Matter
What cannot be created or destroyed but can be transferred?
What is energy?
Temperature in Canada is measured in degrees ____________.
What is celsius?
Name an example of a structure.
What is table, you, house, Eiffel Tower, etc.?
Name the 3 parts of the earth. (Chemical composition)
What is crust, mantle, core?
Living organisms in an ecosystem are called abiotic. True or false.
What is false? They are called biotic.
What are heterogeneous mixtures?
What are mixtures where you can see the different parts?
Is the statement true or false?
Heat and temperature is the same thing.
What is false?
Heat is the transfer of energy from one place to another due to a difference in temperature.
Temperature is a measurement of how fast particles move.
What is an object's centre of gravity?
What is the place where an object is equally balanced on all sides?
What are the 5 layers of the earth? (Physical properties)
What are lithosphere, asthenosphere, mesosphere, outer core, inner core?
Name 3 abiotic factors in an ecosystem.
Mixtures that look the same throughout are called homogeneous mixtures or ______________.
What are solutions?
Name the three ways that heat transfers between objects.
Name the 3 kinds of structures.
What is shell, frame, and solid?
Name the 3 types of boundaries and briefly explain them.
What is:
1. Divergent boundaries: plates pull apart.
2. Convergent boundaries: plates push together.
3. Transform boundaries: plates grind past each other.
A forest fire is an example of a primary or secondary succession?
What is a secondary ecosystem?
Name the difference between a pure substance and a mixture.
What is pure substances are made of one type of element or compound and mixtures are made of 2 or more that are not chemically combined?
Name 2 places where convection currents happen.
What is in the sun and what is in the asthenosphere of the earth?
Name a difference between structural fatigue and structural failure.
What is structural failure means the object breaks apart but structural fatigue means the object is damaged?
Explain the theory of plate tectonics. (FULLY)
(Theory and explanation as to why it happens)
What is that the earth is divided into continents and oceans that are on hard rock called plates. The plates are moving because they are riding on the asthenosphere which is a semi-liquid layer?
What is a producer? And what process does it use to make energy?
What is something that uses sunlight to produce its own food? What is photosynthesis?
Name 4 out of the 5 parts to the particle theory.
What is:
1. All matter is made of tiny particles.
2. Particles are always moving. Particles move faster when heater and slower when cooled.
3. Particles are never touching, they always have spaces between them.
4. Pure substances are made of 1 type of element/compound and mixtures are made of 2 or more.
5. Particles are attracted to one another.
Explain how convection heat happens using the particle theory.
What are 3 things that engineers do to keep skyscrapers from failing?
What is they use dampers, they make strong foundations with deep pillars, they change the shape of the building to confuse the wind, they take in the wind and convert it to energy for the building?
What is:
1. Sedimentary: through weathering and erosion, sedimentation
2. Metamorphic: heat and pressure
3. Igneous: melting then cooling and hardening
Give me a food chain with an example of each:
- producer
- primary consumer
-secondary consumer
- scavenger
- decomposer
What is grass, cow, me, coyotes, fungi?
