What three "ingredients" make up weather?
water, air, and heat/temp
What powers weather?
List the five layers of the Earth's atmosphere starting closest to Earth.
Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere(Tell Sally My Thermometer Exploded)
What is one important feature of the troposphere?
It is where weather occurs
What is one important feature of stratosphere?
The ozone is located in it
What is one important feature of the mesosphere?
Meteors fly in here
What is one important feature of the thermosphere?
It's the hottest layer
What is one important feature of the exosphere?
Satellites fly here, beyond is outer space
How does the atmosphere of the early Earth differ from today's atmosphere? What caused the change?
The early atmosphere didn't have any oxygen, and the atmosphere now has some oxygen in it because of photosynthesis.
How are hurricanes and tornadoes different?
Tornadoes form on land and in water, but hurricanes form only in water.
How do tornadoes form?
Tornadoes form when warm and dry air meet, creating instability in the atmosphere. The wind changes direction and the speed increases. This creates an invisible spinning effect. Rising air within the spinning tilts the rotating air from horizontal to vertical.
How do hurricanes form?
They form over the ocean. Swirling low pressure systems that flow over warm water formed by heat energy from water turning into wind energy.
What causes thunder and lightning?
The movement of electrons.
How can you stay safe during a tornado?
Get in an underground area, stay away from windows, or stand in a doorway.
How can you stay safe during a hurricane?
Stay in a room with no windows, and find shelter.
How are weather and climate different?
Climate is the average weather of a place over the course of around 30 years. Weather is the day by day weather of a place.
What causes different climates on Earth?
The Earth is tilted on its axis so as it turns, different parts of the Earth gets direct sunlight. The Equator always gets direct sunlight.The poles do not get direct sunlight.
How does the Earth's tilt effect seasons and climates?
The tilt of the Earth causes the seasons. When the Earth tilts, the area closest to the Sun will be in a hotter season.
Within the same latitude why do we have different climates?
As you get closer to the Equator, it gets hotter, causing different climates, even within the same latitude. Also, large bodies of water, big cities, and mountains impact the climate.
Name two climates from the low, middle, and high latitudes.
Low: Rainforest, Desert
Middle: Steepe, Chaparral
High: Alpine, Tundra
Does air have mass?
What causes wind?
The uneven heating of Earth and its atmosphere.
What happens to air when it is heated?
Air rises when it is heated, and sinks when it is cooled.
What is the Coriolis Effect?
Wind can't be blown straight up and down because of the rotation of Earth deflects it.
