States of Matter
What are the 3 states of matter?
Solid, Liquid and Gas
What happens when humidity reaches 100%?
Water particles combine and create rain
Low density means the particles are......
far away from each other and are less heavy
What is weather?
short-term conditions of the atmosphere at a particular time or place
What is a Cold Front?
Cold air replaces warm air--> rains and storms--> cold weather
How do you change a solid to a liquid?
By adding heat/ melting
What is Humidity?
The amount of water vapor in the air
High Density means the particles are
close together and tightly packed making it heavier
Wind is created when....
air moves from high pressure to low pressure
What is a Warm Front?
Warm air replaces cold air --> light storms ---> warm weather
Evaporation vs Condensation
E: Particles heat up and move away from each other
C: Particles cool down and connect together
What is percipitation?
any water that comes from the sky.
Rain, snow, hail, or sleet
What density is cold air?
High
What is Climate?
a description of the long-term weather in a particular area
What is a High Pressure System?
Cold air sinks down and it gets warmer. creates clear and blue skys.
What is the term for when a solid turns to a gas?
Sublimation
How do clouds affect the temperature during the day?
Clouds reflect he heat from the sun back into space creating cooler days
What density is hot air?
low density
Cold temperatures mean particles are.....
moving slowly and staying close together
What is a Low Pressure System
Hot air rises and gets colder. creates cloudy and rainy skys.
What do the particles do when a liquid changes to a solid?
Slow down and connect
How do clouds affect the temperature during the night?
Clouds reflect the heat from the earth back to the earth creating warm nights.
Air Pressure Vs Density
P: The weight of the air
D: how tightly packed particles are
Warm temperatures mean particles are....
moving fast and spread out
A High Pressure System usually comes with a _____ front.
warm front
