Question | Answer |
What are the three types of global winds? | trade winds, the westerlies, and the polar winds. |
Prevailing winds blow from 30 degrees toward the equator. | trade winds |
Prevailing winds that blow from the southwest in the Northern Hemisphere between 30 and 60 degrees | westerlies |
Prevailing winds that blow from the northeast in the Arctic | polar easterlies |
High speed winds near the top of the troposphere in a narrow belt are known as | the Jet Stream. |
Maritime air mass forms over | water |
Continental air mass forms over | land |
Across North America, warm air masses generally move | north and northeastward. |
Across North America, cold air masses move | south and southeastward. |
narrow zone of transition between air masses that differ in temperature or humidity. | front |
the leading edge of an advancing cold air mass forces itself under and pushes up a retreating warm air mass. | cold front |
Since cold fronts move fast they often result in | in severe weather. |
When a warm air mass rises over top of a cold air mass a ________ front is formed | warm front |
front that occurs when when a warm and cold air mass collides and there is not enough energy for movement | stationary front |
two cold air masses force a warm air mass up. (a warm front and cold front collide) | occluded front |
high altitude, wispy clouds made of ice crystals. | cirrus |
low, flat layered grey clouds that often bring a drizzle. | stratus |
thick, puffy white clouds with flat bottoms. | cumulus |
dark towering cumulus clouds that bring lightening and heavy rain. | cumulonimbus |
A thermometer measures | temperature |
An anemometer measures | wind speed. |
A rain gauge measures | rainfall. |
second layer of the atmosphere, contains the ozone layer | Stratosphere |
third layer of the atmosphere. | Mesosphere |
It is the coldest layer of the atmosphere. | mesosphere |
highest, hottest and largest layer | Thermosphere |
________________contains the exosphere which is the outer most reaches of the atmosphere | thermosphere |
is a shift in the winds caused by a rotation in the earth. | Coriolis Effect |
Local winds are caused by geographical features such as | a mountain, lake or an ocean. |
High speed winds near the top of the troposphere in a narrow belt are known as | the Jet Stream. |
measures rainfall. | rain gauge |
group of the same species that lives in an area at the same time. | population |
characteristics of an ecosystem that determine how large a population can get. | Limiting factors |
The largest size a particular population that can be supported by a particular environment is the environment’s | carrying capacity. |
close long term association between two or more species. | Symbiosis |
symbiotic realtionship where both organisms benefit. | Mutualism |
symbiotic realtionship where one benefits and the other is unharmed. | Commensialism |
where one organism benefits while the other is harmed or killed. | Parasitism |
group of animal and plant populations living together in the same environment. | community |
Changes in communities occur over time in a process called | ecological succession. |
a series of slow, predictable changes in the number and kinds of organisms in an area. | Succession |
succession when organisms begin to inhabit an area that had no life or soil. | Primary |
succession an existing community suffers a major disruption but soil is present. | Secondary |
is the study of the relationship between organisms and their environment. | Ecology |
is made up of a community and its abiotic (non-living or physical) environment. | ecosystem |
word that means it is non-living. | abiotic |
examples of abiotic factors | climate, soil, water, air, nutrients, and energy. |
examples of biotic factors | living substance. Plants, animals, fungus, bacteria, etc. |
The_____ is the ultimate source of energy for most ecosystems. | sun |
organisms that make food by the process of photosynthesis. | Producers |
Most producers are | green plants and algea. |
Examples of primary consumer | plant-eating animals. |
Examples of secondary consumers | predators, eat animals. |
organisms that break down dead plants and animals into simple nutrients. | Decomposers |
The model that shows ONE series of energy changes goes through as it is passed from one organism to another is called a | food chain |
A _________is overlapping networks of food chains. | food web |
The energy pyramid is a model that shows | how much energy passes through organisms |
The model that shows that as consumer energy needs increase populations decrease is an ecosystem | energy pyramid |
when water falls to earth in any form: rain, snow, hail, or sleet. | Precipitation |
water vapor cools and changes back into liquid droplets, forming clouds. | Condensation |
when liquid water changes into a gaseous form called water vapor. | Evaporation |
when water vapor is released through opening in the plant’s leaves called stomata | Transpiration |
when water, usually from precipitation, flows across the land and collects in rivers, streams then eventually lakes and oceans. | Run-off |
The energy for the water cycle comes from | the sun. |
Photosynthesis is the only process in the carbon cycle when carbon is | taken out of the environment. |
In photosynthesis plants use carbon dioxide and water to make | their own food and release oxygen. |
Organisms use the food and oxygen, created during photosynthesis, for energy | Respiration |
Organic material is burned and carbon dioxide and monoxide are released. | Combustion |
Nitrogen (cannot/can) be used by plants in its natural form | CANNOT. |
Nitrogen is fixed by | bacteria in the soil and lightning |
making wise choices with the resources we have | Conservation |
methods include reducing how much we use, reusing resources when possible and recycling products so the resources are still available to us. | Conservation |
everything not made by humans that can be used by organisms. | Natural resources |
can be replaced relatively quickly such as trees and water. | Renewable resources |
Fossil fuels such as coal, oil, and natural gas are from | the remains of once living organisms. |
Obtaining and using fossil fuels can cause many environmental problems such as | global warming, water pollution acid rain and smog. |
Most people use fossil fuels because | often cheaper or more convenient |
Burning fossil fuels puts large amounts of carbon dioxide in the atmosphere which may | increase greenhouse effect creating global warming |
Alternative energy sources are being developed to help minimize problems from fossil fuels such as | using the sun, wind, moving water,and the heat of the earth |
the amount of matter that makes up an object. | Mass |
Unit mass is measured in | grams |
the force of gravity acting on the mass of an object. | Weight |
Weight is measured in what metric unit? | Newtons. |
the amount of space occupied by an object. | Volume |
liquid volume is measured with | a graduated cylinder using liters. |
substances that take the shape of their container, liquids and gases are______ | Fluids |
an upward force produced by fluids. | Buoyancy |
The greater the density of the fluid, | the greater the buoyant force. |
Archimedes’ principle states that the buoyant force on an object is equal to | the weight of the fluid the object displaces. |
If the object displaces its own weight of the fluid it is in it | will float. |
the mass of an object compared to its volume. | Density |
What is measured in grams per milliliter? | Density |
Objects with a density greater than the fluid it is in will (float or sink)? | sink |
something that allows a body to do work. | Energy |
Energy cannot be created or destroyed, it changes form is the law of | law of conservation of energy |
resistance of a body to a change in its state of motion. | Inertia |
the energy of motion | Kinetic Energy |
stored energy due to position (gravitational) or changing shape (spring or bow). | Potential Energy |
push or pull on an object that will change its state of motion. | force |
Speed is calculated by | (S= Distance ÷ Time) |
a force that works against a moving object. | Friction |
Before starting a lab or activity | study the procedure. |
What accident or injury should be reported? | any |
the predicted answer to a scientific question. | hypothesis |
In a controlled experiment _______ variable(s) should be tested at a time. | 1 |
a simple representation for something complex. | model |
Factor in the experiment that is purposely changed to test a hypothesis. | independent varialble |
Factor that may be affected by the one you are testing | dependent variable |
A(n) ____________is factual information gathered with any of the five senses. | observation |
_________ is a conclusion made from observations | inference |
A _______ observation can be measured or counted | quantitative |
