Sedimentary Rock Formation
Which process of sedimentary rock formation explains this: pressure causing layers of sediment to form over time.
Compaction
A mixture of salt and water is stirred for 15 seconds. What will the student observe after 15 seconds?
The salt will dissolve in water and the water will remain clear.
What causes the day and night cycle on Earth?
Earth's rotation on its axis
What property of light allows a mirror to work?
Reflection
What is an inherited trait?
A trait you are born with.
Which process of sedimentary rock formation explains this: water carrying rocky material to a new location.
Erosion
I have 3 things in a cup. Oil, a penny, and water. Organize these things from LEAST dense to MOST dense.
Oil, Water, Penny
What direction does the sun rise? What about sun set?
What property of light makes it appear as if a fish is closer to the surface of a lake than it actually is?
Refraction
What three things does a circuit need in order to work?
A power source (battery), wires, and an object to power (bell/lightbulb).
Which process of sedimentary rock formation explains this: wind and rain breaking rocks down in to smaller pieces.
Weathering
As water is cooled, it ___________ and changes from a ______ to a _______.
Condenses, gas, liquid
How do invasive species affect ecosystems?
They overgraze the land, the cause native animals to die off, or they eat too many of the native animals.
How are U-shaped valleys and V-shaped valleys formed?
U-shaped=glaciers, V-shaped=rivers.
What are the three main nonrenewable resources?
Oil, Coal, and Natural Gas
Which process of sedimentary rock formation explains this: chemicals in water gluing sediment to each other.
Cementation
What are the 3 magnetic metals?
Iron (steel), cobalt, and nickel.
Label the following as either a producer, consumer, or decomposer: bird, mushroom, caterpillar, grass.
Bird=Consumer, Mushroom=Decomposer, Caterpillar=Consumer, Grass=Producer
How are deltas formed?
The deposition of sediments by a slow river.
Describe what a carnivore, herbivore, and omnivore eat.
Carnivore=meat (other animals), herbivore=plants, omnivore=both meat (other animals) and plants.
What are the 5 processes of sedimentary rock formation in order, starting with weathering?
Weathering, Erosion, Deposition, Compaction, and Cementation
What is the difference between an electrical conductor and an electrical insulator?
Conductors allow electricity to flow freely, insulators slow down or stop the flow of electricity.
Describe how fish interact with a living and a nonliving part of its ecosystem.
Living: Fish swim with other fish, they eat other fish, they can eat insects.
Nonliving: Fish hide in their rock/house, they swim in water, they breathe in oxygen.
Why would there be fossils of a shark in the middle of a desert? (hint: what do fossils tell us?)
That desert used to be an ocean.
Fossils tell us what the environment was like millions of years ago.
What four things are needed to make fossil fuels?
Heat, pressure, organic matter, and millions of years.
