Nitrogen Cycle
What is nitrogen in its gaseous form?
N2
Which process do plants use to convert sunlight into chemical energy?
Photosynthesis
What step in the scientific method involves summarizing data to form conclusions?
Data Analysis
Which layer of the Earth is primarily in a liquid state?
Outer Core
Which Earth reservoir stores the majority of the planet's water?
Oceans
Which reservoir holds the largest amount of nitrogen on Earth?
Atmosphere
How do human activities mainly disrupt the carbon cycle?
Increasing CO2 emissions by burning fossil fuels
What is systematic inquiry based on empirical testing called?
The scientific method
Which layer of the Earth is the thickest in terms of volume?
Mantle
Which process moves water from plants to the atmosphere?
Transpiration
Which is a living reservoir for nitrogen?
Plants/Animals
What best contrasts cellular respiration with photosynthesis?
Cellular Respiration breaks down glucose to release energy & CO2.
Photosynthesis stores energy by transforming CO2 into glucose.
