Scientific Method
We use our 5 senses to observe and analyze the natural phenomena of the world.
Observation
____________ is when gas cools turns into water droplets
condensation
This sphere is the region of earth where life exists, including land, water and the atmosphere. It is the where all living organisms and their interactions with the environment occur.
Biosphere
This is the layer closest to the surface of the earth, where weather occurs
Troposphere
Rain, sleet, hail are all examples of ______________
precipitation
This is a statement that starts with "if...., then". Scientists develop a testable explanation or prediction for a phenomenon. It is a educated guess that can be tested through experiment/ investigation
Hypothesis
Which form of heat transfer is responsible for the formation of winds?
convection
This sphere has rocks, land, and soil. It is the solid outer part of earth, including the crust and upper mantle.
Geosphere
This layer of the atmosphere contains the ozone layer and protects all life on earth.
Stratosphere
What is the force that pushes on air molecules?
Differences in air pressure would cause what?
air pressure
wind
An organized procedure to study something under controlled conditions. There are many steps to this process and is frequently repeated to see if a hypothesis is supported or rejected
Experiment
What is the main cause of local winds?
the uneven heating and cooling of land and water.
The frozen parts of earth such as glaceries, ice caps, and all forms of ice.
Cryosphere
The atmosphere contains 78% _______, 21%______ and 1% other gases. (In order)
Nitrogen, oxygen
The condition of the atmosphere at a particular place and time
weather
Uses the information gathered to determine if the hypothesis was correct
When you step out of the shower, your feet transfer thermal energy to the floor as soon as you step on it. This form of heat transfer is called ___.
conduction
All of the water on earth, including oceans, lakes, rivers and groundwater. it is essential for life and the planets weather patterns.
Hydrosphere
This layer is the hottest layer of the atmosphere.
Thermosphere
A large body of air with similar temperature, humidity and air pressure that forms over land or water.
air mass
The factor that changes as a result of manipulation of one or more variables
The variable that doesn’t change and is deliberately manipulated by the experiment
Independent variable and dependent variable
What is the main source of energy that creates the motion in both the atmosphere and ocean?
the sun (radiation)
The layer of gas surrounding the earth, includes oxygen, nitrogen, carbon dioxide and other gases. it plays a key role in protecting life from solar radiation.
Atmosphere
These are the layers of the atmosphere (must name them in order from lowest to highest).
troposphere, stratosphere, mesosphere, thermosphere
Warm air mass meets and rises above cold air masses during this kind of front
warm front
