What are mixtures and solutions?

• Mixtures are combinations of two or more substances that are chemically combined, while solutions are mixtures where one substance does not dissolve in another.

• Mixtures are combinations of two or more substances that are not chemically combined, while solutions are mixtures where one substance evaporates into another.

How are shadows formed?

• Shadows are formed when the sun is directly overhead

• Shadows are formed when there is no light in the area

• When an object blocks the path of light, creating an area of darkness behind it.
