Mixtures and solutions are all over the place, you just have to know
what you are looking for to find them.
We may mix things while in the kitchen, while working outside, or while
doing arts and crafts. However, the end result is not always considered a
mixture.
A mixture is when two or more substances are combined,
but each substance keeps its physical properties, which is a
characteristic that can be measured or observed. Mixtures do not have a
chemical reaction, such as dissolving or burning. Furthermore, a mixture
can be reversed, or separated, after being combined.
Let's take a look at these videos where they explain it to us much better.

Primary sector extracts natural materials and provides raw materials for secondary industry.
Secondary sector processes raw materials or semi-finished goods into more valuable products.
Tertiary sector is the provision of services.
