1130 - What changes can happen to matter or natural phenomena under external influences.

When matter or natural phenomena are affected by external influences, several changes can happen. Here are a few examples:

1. Melting: When ice (or any solid) gets heat, it can turn into a liquid, like water.
2. Boiling: When a liquid gets too hot, it can turn into a gas, like steam.
3. Freezing: When a liquid gets too cold, it can turn into a solid, like ice.
4. Expansion: When things get hot, they often get bigger. Like how a balloon can get bigger when you heat it up.
5. Contraction: When things get cold, they often get smaller. Like how a metal object can get smaller when you put it in the fridge.
6. Rusting: When metal meets air and water, it can start to rust, or turn into a yucky brown color.
7. Weathering: When rocks are exposed to wind, water, and other natural forces, they can break down into smaller pieces.
8. Plants Growing: When plants get sunlight, water, and air, they can grow bigger and stronger.

These are just a few examples of how external influences can change matter and natural phenomena.
