What causes convection currents in earths atmosphere?
Uneven heating of earths surface by the sun
What is similar and different between tropical cyclones, hurricanes, and typhoons
same: forms the same way
different: location
A wildfire burns a forest but leaves soil intact. What type of succession will occur?
Secondary succession.
Which organelle controls what enters and leaves the cell?
Cell membrane.
A bird migrating south for winter is which type of adaptation?
Behavioral adaptation.
A city experiences warmer average temperatures over 30 years due to increased greenhouse gases. Is this weather or climate?
Climate
why do hurricanes weaken after moving over land?
They lose access to warm ocean water energy
A glacier melts and exposes bare rock. What type of succession begins?
Primary succession.
Why do plant cells need chloroplasts?
To perform photosynthesis and make their own food.
A snake producing venom is which type of adaptation?
Physiological adaptation.
Which greenhouse gas is MOST increased by burning fossil fuels?
CO2 (carbon dioxide)
Which combination is MOST likely to strengthen a hurricane?
All three conditions strengthen hurricanes.
Why does secondary succession happen faster than primary succession?
Soil is already present.
How are DNA, genes, and chromosomes related?
Genes are segments of DNA found on chromosomes.
Thick fur on a polar bear is which type of adaptation?
Structural adaptation.
How does the coriolis effect influence global winds?
It causes winds to curve due to earths rotation
How do ocean currents affect climate?
They move warm and cold water, affecting nearby temperatures and precipitation.
How does biodiversity help ecosystems survive natural disasters?
Greater biodiversity increases stability.
Which cell structure is found in plant cells but NOT animal cells and helps provide support?
cell wall
Why are adaptations important for organisms?
They increase an organism’s chances of surviving and reproducing.
How do convection currents help create global wind patterns?
Warm air rises and cool air sinks, creating convection currents that move air around Earth and form global winds.
Why would a hurricane most likely NOT form near cold ocean currents?
Cold water does not provide enough heat energy.
Which event would MOST likely lead to primary succession?
Volcanic eruption
A scientist observes a cell with a cell wall, chloroplasts, and a large central vacuole. Which type of cell would they be observing?
Plant cell
A desert kangaroo rat can survive with very little water by producing concentrated urine. What type of adaptation is this?
Physiological adaptation.
