Absorption: Soaking up a particular substance, either a liquid or gas. It’s what a towel does to the water on your body when you dry off.
Capillary action: The ability of a liquid to flow in narrow spaces without the help of gravity. This ability is due to attractive forces between molecules. It’s why blood can flow through the narrowest veins and capillaries in our body.
Climate: The average weather in a given area over the course of several years. For example, a desert has a dry climate, and a tropical rainforest has a hot, wet climate.
Material science: The discovery or creation of new materials, usually solids.
