The movement of sediments and soil by wind, water, and gravity.
What is erosion?
100
Everyone needed to make sure they had only _____ variable changing in their experiments.
What having one variable?
100
Anything that has mass and takes up space.
What is matter?
100
A push or pull.
What is a force?
200
All members of one kind of organism that live in an area. Example, all the white-tailed deer in a forest.
What is a population?
200
This landform is formed from sediments being deposited at the mouths of rivers
What is a delta?
200
In a controlled experiment it is the variable that is being tested.
What is the manipulated or independent variable?
200
We can use these to describe and compare solids, liquids, and gases.
What are physical properties (volume, shape, movement and spacing of particles)?
200
This is the result of a change in force or a change in mass.
What is motion?
300
These are the 2 main types of ecosystems.
What are terrestrial and aquatic?
300
This type of landform is created from the movement of wind and water
What is a canyon?
300
A prediction about the relationship between variables. All controlled experiments should have one.
What is a hypothesis?
300
Increase the temperature, decreases particle size, or stirring.
What are ways we can make solutes dissolve faster?
300
A stopping force that is produced when objects are in contact with each other. It acts against motion and may be reduced by using lubricants such as oil or water.
What is friction?
400
Resources (food, water, shelter, space) that affect populations in ecosystems.
What are limiting factors?
400
Breaks it, Takes it, Drops it!
What are weathering, erosion, and deposition?
400
Your experiments were testing these different types of forces
What are gravity, friction and magnetism?
400
When salt dissolves in water salt is know as the ________ and water is called the __________.
What are solute and solvent?
400
The force that causes objects with mass to attract one another
What is gravity?
500
An organism that makes its own food through the process of photosynthesis
What is a producer
500
Give one example for each of the following:
Weathering
Erosion
Deposition
What is a canyon, glacier, and sand dune
500
In order to make sure that you are measuring correctly, you need to __________
What is repeated trials?
500
The relationship between the freezing point of a liquid (water) and melting point of a solid (ice).
