Unit 1
Identify an example of a natural source of pollution.
water pollution
Describe three types of models used by scientists.
Physical models ,Conceptual models ,Mathematical models
Explain the three mechanisms of heat transfer in Earth’s atmosphere
radiation. conduction. convection.
_____________ don’t evolve, populations do
Individuals
What is an abiotic factor
a non living part of an ecosyten
Explain why critical thinking is an important skill in environmental science.
Because human intuition is a terrible mechanism for actually understanding the way nature actually works
Explain why sample size is important in determining probability.
the number of objects is too small to yield inaccurate results
Explain the main cause of earthquakes and their effects.
sudden tectonic movements in the Earth's crust
__________ Large scale changes. involves speciation
Macroevolution
What is a biotic factor
Living or once living part of the environment
Describe the major environmental effects of the agricultural revolution and the Industrial Revolution.
Industrial- The world saw a major increase in population, which, along with an increase in living standards, led to the depletion of natural resources.
agricultural- transforming forests and previously undisturbed land into farmland, destroyed habitats, decreased biodiversity and released carbon dioxide into the atmosphere.
Explain what “the mean number of weeds in three plots of land” means.
that the results from three different plots were averaged together.
Name and describe the physical and compositional layers into which scientists divide the Earth.
Inter core, Outer core, Mesosphere, Asthenosphere, Lithosphere, Core, Mantle, Crust
__________ changes in alleles frequencies in a population over generations
Microevolution
Describe a population
as a group of individuals of the same species living and interbreeding within a given area
Explain how hunter-gathers affected the environment in which they lived in
They burned prairies to keep them open grasslands to hunt bison. This destroyed environments and over hunting killed off some animals.
Explain how scientists try to answer questions that cannot be tested with experiments.
Testable questions are answered by collecting and analyzing evidence and developing explanations based on that evidence. Questions that cannot be answered through scientific investigation are those that relate to personal preference, moral values, the supernatural, or unmeasurable phenomena.
Describe a characteristic of each layer of the atmosphere.
These layers are the troposphere, the stratosphere, the mesosphere, and the thermosphere
Who is the geologist that proposed a theory of slow uniform geological change.
James Hutton
What is the end results of photosynthesis
Glucos
Explain how environmental problems can be local, regional, or global. Give one example of each.
A local example would be your community discussing where to build a new landfill. A regional example would be a polluted river 1000 miles away affecting the region's water. A global example wouldbe the depletion of the ozone layer.
How do you find mean?
add up all the numbers, then divide by how many numbers there are
Describe the role of greenhouse gases in Earth’s atmosphere.
trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere
Who is the geologist who used Hutton’s idea in his book about deep time, Principles of Geology
Charles Lyell
Describe the role that producers play in an ecosystem.
make food on their own by capturing energy from sunlight and make that available to all the other living parts of ecosystems and food chain starts
