9
In which atmospheric layer is the ozone layer located?
Stratosphere
Which type of heat transfer occurs through the movement of liquids or gases?
Convection
Which process releases water vapor from plant leaves?
Transpiration
What is the group that does not receive the independent variable and is used for comparison?
Control group
A temperature changes from 20C to 25C to 20C to 35C. What trend does the data show?
The temperature is increasing
In which layer do most meteors burn up?
Mesosphere
The warm ground heats the air touching it. Which type of heat transfer is occurring?
Conduction
After rain, water flows over land into a river. What is this called?
Runoff
A student changes the amount of sunlight plants receive and measures their growth. Identify the independent and dependent variables.
IV: Amount of sunlight
DV: Plant growth
A student wants to compare the number of classmates who prefer Coca Cola, Pepsi, Dr. Pepper, or Sprite. Which type of graph should the student use? Bar graph or line graph?
Bar graph
Put these layers in order from lowest to highest: mesosphere, troposphere, thermosphere, stratosphere
Troposphere --> Stratosphere --> Mesosphere --> Thermosphere
Energy travels from the Sun to the ground. The ground heats the air touching it, and the warm air rises. Name the three methods in order.
Radiation --> Conduction --> Convection
What provides the energy that drives evaporation and the water cycle?
The Sun
