What is decomposition?
The process of breaking down
What is synthesis?
The process of putting things together
What is solubility?
The amount of solvent that be can be dissolved into a solute
What is a pure substance?
It is an element that is made up of only one component
What is a heterogeneous mixture?
It is a mixture where you can see the different components with a naked eye
What is a homogeneous mixture?
It is a mixture where you can’t see the different components
Chemical changes (6)
Formation of precipitate/ change in colour/ formation of gas/ mold or rust/ release or absorption of heat/ emission of light
Energy (10)
Kinetic energy: thermal energy/ mechanical energy/ electrical energy/ magnetic energy
Potential energy: chemical energy/ elastic energy/ nuclear energy / gravitational energy
What is a multiview projection?
A projection showing all sides of an object (2D)
What is an Isometric projection?
3D view of an object as the point and three visible sides that are no on the plane or the paper no side facing towards you
What is an oblique projection?
View of an object that has only 1 face in the paper plane (facing you) while the other sides are out of the paper
What are the different types of fossils?
- Petrified
- Cast/Mould
- Body
- Trace
Where are fossils found?
Found in Sedimentary rocks
How are fossils and stratigraphic layers connected?
Both principals apply to fossils as well. Fossils found in the same layer are from the same time period. Older fossils are in the deeper layers .
What is relative dating?
Method used to place fossils in order without finding their exact age
