Question

match each example with the subsystem it belongs to
igneous rocks oceans frozen lakes gaseous nitrogen sea animals
marine plants
hydrosphere geosphere atmosphere biosphere

Explanation:

• Hydrosphere: This subsystem encompasses all water on Earth. Oceans are large bodies of salt - water, and frozen lakes are bodies of freshwater in a solid state (ice), so they belong to the hydrosphere.
• Geosphere: It includes the solid Earth. Igneous rocks are a type of rock formed from the cooling and solidification of magma or lava, so they belong to the geosphere.
• Atmosphere: This is the layer of gases surrounding the Earth. Gaseous nitrogen is a major component of the Earth's atmosphere (about 78% of the atmosphere is nitrogen gas), so it belongs to the atmosphere.
• Biosphere: It is the global sum of all ecosystems, including all living organisms. Sea animals and marine plants are living organisms, so they belong to the biosphere.

Answer:

• Hydrosphere: oceans, frozen lakes
• Geosphere: igneous rocks
• Atmosphere: gaseous nitrogen
• Biosphere: sea animals, marine plants
