100
The icy part of Earth.
What is the cryosphere?
100
it is open to change.
Why is science durable?
100
So that other scientist can follow your procedures and get the same results.
Why must scientific investigations be replicable?
100
The hydrosphere.
What is the liquid part of the Earth called?
100
The geosphere.
What are the rocks, minerals, and landforms of the Earth called?
200
So that she can develop explanations that fit the evidence generated by her investigation.
Why must a scientist be creative?
200
Science relies on this instead of opinion.
What is evidence?
200
This variable of an investigation must not be allowed to change.
What is constant, or controlled, variable?
200
These are the two types of weathering.
What are physical and chemical weathering.
200
Single-celled and multicelled organisms.
What are the two types of organisms?
300
This form of heat transfer uses electromagnetic waves.
What is radiation?
300
This type of heat transfer occurs when air, or liquid, is heated making it expand, become less dense, and rise.
What is convection?
300
This type of heat transfer occurs with direct contact (touching) of particles. It also occurs within an object.
What is conduction?
300
This is an idea (perhaps unprovable) which explains observations of the natural world.
What is a scientific theory?
300
This type of heat transfer causes sea and land breezes after the sun warms things up.
What is convection?
400
This is the movement of thermal energy (heat) from a hotter object to a cooler object.
What is heat transfer?
400
This is the variable of an investigation that I change.
What is the independent, or manipulated, variable?
400
This is the variable of an investigation that I measure.
What is the dependent, or responding, variable?
400
This is the movement of weathered material from the site of the weathering.
What is erosion?
400
This happens when a river slows down enough for gravity to pull sediments down to the bottom. Sometimes a delta is formed.
What is deposition?
500
Name the three parts of the cell theory.
What is: (1) all organisms are made of one or more cells. (2) the cell is the basic unit of all living things. (3) all cells come from existing cells
500
This type of breeze occurs when convection causes the air above the land to expand, become less dense, and rise.
What is a sea breeze?
500
This is a measure of how hot or cold something is.
What is temperature?
500
When water freezes in a crack of rock, causing the rock to split, it is called this type of weathering.
What is physical weathering?
500
A delta is an example of this.
What is deposition?
