They take millions of years to form
Light rays bouncing off a smooth, shiny surface is called
what is Reflection
This process drops off sediments in new locations.
What is Deposition?
What is the difference between a Mixture and a Solution?
A mixture is usually easily separated and you can see the ingredients or part. A solution one thing spreads out evenly in another and hard so separate.
An organism that eats other organisms for energy.
What is a consumer?

An open circuit means the light will be...
off
If the sun is setting, what direction is it in.
West
Light travels in a ________________

They prevent or stop energy from passing through easily.
What is an Insulator?
Give an example of a biotic element interacting with an abiotic element in an ecosystem.
A fish swimming in the ocean. A rabbit hopping on a sandy path. etc.
A U-shape valley is made by?
The movement of a glacier
What causes the day and night cycle?
Earth rotating on its axis
How long does it take for Earth to orbit the sun?
365 days
Process of water vapor cooling down to a liquid
What is condensation?
What is friction?
A force that resists motion, more of it slows things down.
This process is where plants lose water vapor through their leaves.
Transpiration
What causes the four seasons (fall, winter, spring, and summer)
The tilt of the Earth as it orbits or revolves around the Sun.
What is it called when light bends as it moves from one medium to another?
Refraction - lens bends
What do waxy coating and scaly skin have in common?
They both help retain water.
Give a structure of an animal that lives in a desert and explain how it helps it survive.
Large ears to control body temp, Light brown colored fur for camo, thick fur on feet prevent burns, burrowing
made from decomposing plants and animals over millions of years
What are Fossil fuels?
The sun appears to move across sky. Why?
The earth is spinning on its axis so it looks like the Sun is moving (Apparent motion of the Sun)
A substance that was mixed with water and is no longer visible. We say this substance is ___________in water.
Soluble
Long term weather patterns usually over 30 years.
What is climate?
This is what an organism who breaks down dead things is called
What is a decomposer?
What is the order of the formation of sedimentary rock?
Weathering, erosion, deposition, compaction, cementation
What is an Independent variable?
A variable that changes.
What made a V-shape valley?
Moving water in a river
This forms from the dirt, rocks, and sediment a river carries and drops off as it slows down and enters an ocean.
A delta.
The movement of sediment by wind, water, or ice.
Erosion
What creates the appearance of sun moving?
Earth rotating on its axis. (did you know it makes the stars look like they are moving too?
What is an herbivore, carnivore, and omnivore?
Herbivore eats plants, carnivore eats meat, and an omnivore eats plants and meats.
What makes a canyon?
Weathering and erosion by water (a river) (usually through a plateau)
Why are producers so important in a food web?
Because they turn the sunlight into the energy that every other living thing needs to survive. If they weren't there no living thing would have food.
You have a table, a lamp, and a teacher chair. What should you do to model earth's rotation?
Put the lamp on the table and sit on the chair. Then spin on the teacher chair to model day and night.
What is the breaking down of rock called?
Weathering
Formed by the erosion and deposition of sand by the wind.
Sand dune
What could be added to a glass of room temperature water to cause condensation to form on the outside of the glass?
Ice cubes or much colder water
Chemical energy forms:
food --changes to mechanical/heat energy in our bodies
Fuel -wood and fossil fuels can change to heat or elec
What is the third that could power a remote control car?
Batteries- have chemicals inside and can cause change such as movement, light, sound, and heat.
What are the moon phases starting with new moon AND explain how they are "lit up"?
New- nothing, 1st quarter- lit on right, Full moon- fully lit, Last (3rd) quarter- Lit on Left (lit left last
What is the tested property where we see if it sinks or floats in water? (2 words)
Relative density
A plant that lives low to the ground, has very large leaves, and sometimes a drip tip, can be found in what type of habitat? Why do they have a large leaves AND/OR the drip tip?
A rainforest and the reason is to collect sunlight and when it shines through to the forest floor and a drip tip so that the water doesn't sit on the leaves.
How do we see colors?
The color of the light rays that bounce off and back to our eyes is what we see. Everything else gets absorbed. (White -- all rays bounce back. Black -- all rays soak in.)
