Behavior of Light Energy
What happens when light strikes a mirror?
It bounces back at the opposite angle.
Are fossil fuels renewable or nonrenewable?
nonrenewable
What determines if it is summer or winter?
The tilt of the Earth on its axis
Jonathan pulls his chair out to sit down. Is that an example of a balanced or unbalanced force?
Rain, hail, sleet, and snow are all this
What is precipitation?
Light can do 3 things when it hits a surface. What are they?
Reflect, Refract, or absorb
an energy source that has a continuous supply (solar power, wind power)
What is Renewable?
Name 3 landforms.
Cave, delta, canyon, mountain, underwater volcano, volcano, river, lake, sand dune, u shaped valley, v shaped valley, etc.
In an experiment measuring how fast a car will go on a ramp, what needs to be changed and what needs to be measured?
The height of the ramp and the distance of the car.
Boiling water changing to water vapor is an example of what?
evaporation
Name a tool that uses refraction to help us see things better.
lens, glasses, binoculars, telescope,
If fossil fuels are found, what was the environment like before they were formed? A shallow sea or a desert
A shallow sea where plants and animals lived
the earth revolves around this object
What is the Sun?
What is the controlled (constant) variable?
All the things in the experiment that you want to keep the same. What is not being changed or measured.
Water droplets form on a piece of glass above a boiling pot of water. What process causes this?
Condensation
What happens when light moves from air into water or from water into air.
When light moves from air to water it slows down and bends causing objects under water to look different.
When light moves from water to air it speeds up.
What is required to make fossil fuels in sedimentary rock.
organic material (dead organisms/sea plants and animals)
What is the difference between rotation and revolution?
The Earth rotates on its axis while it revolves around the Sun.
What is a dependent variable?
The thing that you are measuring in an experiment.
Name all the steps in the water cycle.
Evaporation, condensation, precipitation, runoff, collection, percolation, and transpiration.
light hits a mirror at an angle of 30 degrees, what will be the angle of the reflection?
150 degrees
Name all the steps in the sedimentary rock cycle
weathering, erosion, deposition, compaction, and cementation
This is formed when sediments are deposited at the mouth of a river joining a larger body of water.
Delta
What is an independent variable?
The thing that you are changing in an experiment.
Fog is an example of what?
Water Vapor
