Sunlight, air, forests, minerals, and water are all examples of this
What is Natural Resources
This is the procedure that scientists use to test a hypothesis.
What is an Experiment
This is the layer of the Earth between the crust and the core.
What is the Mantle
This is a nonliving part of an ecosystem.
What is an Abiotic Factor
The atmospheric gas that increases when fossil fuels are burned off.
When the last member of a species dies, this has occured.
What is Extinction
When scientists can't use an experiment to test a prediction, this can be examined instead (Darwin's (Blank) of Evolution).
What is a Theory
This is a break in the Earth's crust.
What is a Fault
This is a living or once living part of an ecosystem.
What is a Biotic Factor
What is a Consumer
A country that has rapid population growth, poverty, and reduced life expectancy is said to be this
This is a series of steps used by scientists to identify and answer questions.
What is the Experimental Method
This is the total amount of dissolved salts in the ocean.
What is Salinity
This is the unequal survival and reproduction that results from the presence or absence of particular traits.
What is Natural Selection
This type of succession occurs where an ecosystem previously existed.
What is Secondary Succession
When people can maintain a high standard of living without depleting natural resources, they have achieved this.
What is Sustainability
The chance that an event will happen is known as this.
What is Probability
This is the transfer of energy through space. UV is one kind.
What is Radiation
The ability of one or more organisms to tolerate a particular chemical designed to kill it.
What is Resistance
A final and stable community after succession is called this
What is a Climax Community
The three major categories of environmental problems are loss of biodiversity, pollution, and this.
These are equations used to represent how a scientific process works.
What is a Mathematical Model
Tectonic plates compose this part of the Earth's crust.
What is the Lithosphere
The change in the genetic characteristics of a population from one generation to the next.
What is Evolution
This is the process of breaking down food to yield energy (The opposite of photosynthesis)
What is Cellular Respiration
