Science and Nature
This gas makes up about 78% of Earth’s atmosphere.
What is Nitrogen?
This type of rock is formed from cooled magma or lava, like granite or basalt.
What is igneous rock?
This plant tissue transports water upward from the roots through hollow, tube-like cells called tracheids and vessel elements.
What is xylem?
This phenomenon occurs when deep ocean water rises to the surface due to wind-driven divergence, bringing nutrient-rich water that fuels high productivity.
What is upwelling?
This major ocean circulation system is driven by differences in temperature and salinity, influencing global climate over centuries.
What is thermohaline circulation?
