How do particles move in solids, liquids, and gases.

When you have a solid, the particles are moving but they're vibrating. They're touching each other, moving but they're only vibrating. They're almost immovable so when something is a solid, the atoms and molecules are vibrating but they look like they aren't moving.

For a liquid, the atoms and molecules are moving enough to slide against each other. The speed at which they slide will determine the temperature.

For a gas, there is lots of movement and they're spread out.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
