Light Interactions
Does light travel in straight or wavy lines?
Straight lines
What part of the electromagnetic spectrum is heat?
Infrared light
What kind of cloud causes hail?
Cumulonimbus
What are the 4 main later of Earth?
Inner core, outer core, mantle, and crust
What is a tsunami?
A huge wave around 100ft (30 meters) high that comes ashore.
What is it called when light travels through a material?
Transmission
What three ways is thermal energy transferred?
Convection, conduction, and radiation
What is humidity?
The amount of water valor in the air
Which 2 layers are liquid?
Mantle and outer core
What causes a tsunami? How?
Underwater earthquake. Transfers energy to the water when plates quickly shift past or over each other.
How does light interact with a mirror?
Reflection
List 5 items that would make good thermal insulators
Wood, wool, eraser, cotton ball, air, vacuum, etc...
Why does it not hail in winter?
Winter has low humidity. Any water vapor in the air freezes and becomes a solid
What are the 3 main types of plate boundary? How do the plates interact in each?
Converging - plates move together
Diverging - plates move apart
Transform - plates move adjacent
What is a subduction zone? What boundary is it associated with?
When one plate goes under another. Converging boundary.
How does light interact with clear glass?
Reflection and transmission
How do insulators keep drinks warm or cold?
They slow down thermal energy transfer
What season and time of day does it usually hail? Explain why.
In the afternoon in summertime. High temperatures cause high humidity. Cumulonimbus clouds form and updrafts carry the water vapor into the atmosphere where it cools, condenses, and freezes.
How does convection cause tectonic plates to move?
Hot liquid rock in the mantle rises and pushes cooler liquid rock down.
Where is the safest place to be when a tsunami strikes? Why?
Out at sea on a boat. The crest of the wave will pass safely underneath you.
What does opaque, translucent, and transparent mean?
No transmission, some transmission, almost complete transmission
Describe how convection affects matter. Include thermal energy, kinetic energy, density, rise, and sink.
Matter gains thermal energy, the molecules gain kinetic energy and spread apart. This makes the matter less dense and allows it to rise. Matter loses thermal energy, the molecules lose kinetic energy and the molecules get closer together. This makes the matter sink.
What are the 4 main types of weather front? Describe how the air masses interact and what weather comes along with them.
Cold front: cold air mass pushes a warm air mass up - thunderstorms followed by cooler, dry, sunny weather
Warm front: warm air passes over cold air - long line of clouds and long periods of light rain, followed by warm humid weather
Stationary front: warm air and cold air moving next to each other - cloudy, showers
Occluded front: when two cold air masses push a warm air mass up - long periods of rain followed by cool sunny weather
Which plate does the ring of fire surround? Why is it called the ring of fire? What boundaries would you associate with that?
Pacific plate.
Volcanoes all around it - divergent boundaries
In what region of the USA do we live? Why do we not have to worry about a tsunami hitting us?
Northeast.
There are no tectonic boundaries near to us.
