What is physical weathering?

Back

Physical weathering is the process of breaking down rocks and minerals into smaller pieces without changing their chemical composition. An example is water freezing in cracks of rocks, causing them to break apart.

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, leading to changes in their composition. An example is rusting of iron when exposed to oxygen and moisture.

How many protons are in an atom of Krypton?

Back

An atom of Krypton has 36 protons.

Front

What is surface tension?

Back

Surface tension is the cohesive force at the surface of a liquid that makes it behave like a stretched elastic membrane. It allows small objects, like a paper clip, to float on water.

Front

What is cohesion?

Back

Cohesion is the attraction between molecules of the same substance, which helps to hold water molecules together.

Front

What is adhesion?

Back

Adhesion is the attraction between molecules of different substances, such as water molecules sticking to a glass surface.

Front

What is an atom?

Back

An atom is the basic building block of matter, consisting of protons, neutrons, and electrons.
