This is the layer where we live and where most weather occurs.
Troposphere
As altitude increases, air pressure does this.
Decreases
Provide the steps of the scientific method in the correct order.
Ask a question, research, hypothesis, experiment, collect and analyze data, conclusion, share results.
Heat traveling through direct contact is called this.
Conduction
The word dermatologist contains the root derm. Based on the root, what does a dermatologist study and treat?
Skin
A spacecraft travels outward from Earth through the mesosphere. Name the next two atmospheric layers, in order, that it would pass through.
Exosphere
Air pressure is generally higher at the bottom of a mountain or at the top?
bottom
A student changes the amount of sunlight each plant receives and measures the plants’ growth. What is the independent variable?
the amount of sunlight?
Heat traveling through waves, without direct contact, is called this.
Hydroelectric power uses this substance to help produce electricity.
water
Scientists are concerned about an increase in harmful UV radiation reaching Earth. Which atmospheric layer would they investigate, and what important feature is found there?
Stratosphere
An air mass forms over a large area of land. Would this air mass most likely be moist or dry, and what word describes it?
dry and continental?
A student tests whether the amount of water affects plant height. Every plant receives the same type of soil, same size pot, same amount of sunlight, and same type of plant. What are these factors called?
Constants
The water cycle is an example of what type of heat transfer?
convection
A pseudoscientist may present information that looks scientific but is actually this.
false or fake
A small space rock enters Earth’s atmosphere and begins burning up before reaching the ground. Which atmospheric layer is it most likely traveling through when this happens?
mesosphere
A maritime tropical (mT) air mass moves into North Carolina. What two conditions would you expect it to bring?
warm and moist/humid conditions?
A student tests whether water temperature affects how quickly sugar dissolves. They record the time it takes the sugar to dissolve. What is the dependent variable
the time it takes the sugar to dissolve?
A metal spoon gets hot while sitting in a pot of hot soup. Which type of heat transfer caused the spoon to heat up?
Conduction
A polygon has this type of relationship to sides: it has more than just one or two. The root poly means what?
many
Put these events in order from closest to Earth’s surface to farthest away: auroras occur, weather forms, meteors burn up, satellites orbit in the outermost layer, ozone absorbs UV radiation.
Weather → Ozone/UV absorption → Meteors → Auroras → Satellites in the outermost layer
Two air masses are approaching: continental polar (cP) and maritime tropical (mT). Describe the temperature and moisture of each.
cP = cold and dry; mT = warm and moist/humid.
Students want to know if fertilizer affects plant growth. One plant receives no fertilizer, while the other plants receive different amounts. What is the plant receiving no fertilizer called?
Control group
A pot of water is heated on a stove. The burner heats the bottom of the pot, the water at the bottom warms and rises while cooler water sinks, and you can feel heat from the stove without touching it. Identify the three types of heat transfer occurring and where each happens.
Conduction: Burner → pot through direct contact
Convection: Warm and cool water circulate inside the pot
Radiation: Heat can be felt without touching the stove/pot
A lithosphere is the rigid outer part of Earth made largely of this material.
