What is the difference between the formation of a V-shaped canyon and a U-shaped canyon.
V-shaped canyon is formed by a river. U-Shaped canyon is formed by a glacier.

The sun provides the ___________ that drives the water cycle.
thermal energy
100
What is the difference between renewable and non-renewable energy? Give an example of each.
renewable energy: uses renewable resources to produce energy (ex: solar energy, wind power, geothermal energy, hydropower) non-renewable: The burning of fossil fuels to create energy (ex: oil, natural gas, coal)

What causes the sun to have more gravity than the earth?
The sun is much larger and has a greater mass.
200
What is the difference between a conductor and an insulator of heat? Give an example of each.
Conductors allow thermal energy to pass easily through. Insulators hold energy "in" and do not allow it to pass through easily. Conductor: Metal Spoon Insulator: Wooden Spoon

Describe the process of weathering and give an example.
Breaking/eating rock. The formation of the canyon.
200
What stage of the water cycle is occurring in the clouds?
Water vapor condenses. When enough condensation builds up, the water falls back to the earth as precipitation.
200
Draw a model that represents refraction.
The bending of the light as it passes from one medium to another.
200
________ causes the cycle of day and night.
The rotation of the earth on it's axis.
300
A blacksmith heats metal to the point that is turns to liquid. Once to liquid metal is removed from the heat and placed in a cool location, what state change will most likely occur?
The liquid metal will most likely turn back into a solid.
300
What is formed from deposition of sediment at the end of a river?
A delta
300
Draw a model of the layers of the earth.
Should include: inner core, outer core, mantle, crust.
300
Riding a bike is good example of what type of energy?
Mechanical energy

How does the size of the sun compare to the planets?
It is MUCH larger.
400
A _________ is made of 2 or more substances that combine but retain their physical properties and can be easily separated. A ________ is a special type of mixture that is more difficult to separate and involves one substance __________ into another substance.
mixture, solution, dissolving

What two processes are essential for the formation of sedimentary rock? (hint: they both start with the letter c)
compaction and cementation

What is the difference between weather and climate? Give an example of each.
Weather is the condition of the atmosphere at any given point in time. Climate is the patterns of weather over time. Weather: It is raining outside right now. Climate: The summer in San Antonio is usually hot.

Draw a circuit that is build so that when one light bulb goes out two others will remain lite.
Answers will vary but should include a parallel circuit.
400
What causes the shadow of tree to move throughout the day.
The rotation of the earth causes the sun to appear to move through the sky during the day. This movement creates shadows.
500
Describe what occurs to the molecules in water as it cools from 1 degree celsius to zero degrees celsius.
They lose energy and slow down. Since the water is transitioning to a solid, the molecules will become closely packed together with little space to move around.

Fossils are proof that the earth is ________ (staying the same/changing) over time. The layers located towards the top of the fossil record are the __________. The layers of rock buried towards the bottom of the fossil record are the ______________.
changing, newest, oldest

Where do the drops of water on the outside of your soda can come from?
Water vapor from the air condenses on the cool can.
500
A student builds a circuit with 3 light bulbs. When one bulb goes out, all the bulbs go out. Draw a model of this circuit.
Answers will vary but should include a series circuit.

When a spaceship travels to the moon, what happens to it's mass and weight?
The mass stays the same. The weight will be much less on the moon because weight is the measure of the pull of gravity on an object.
