Explain how matter and energy flow across the boundaries of the four subsystems of the Earth.
Answers
The earth consists of four subsystems, across whose boundaries matter and energy flow, the atmosphere (Air), biosphere (living things), hydrosphere(water) and lithosphere(land). The lithosphere consists of the ground formations we walk on, the inner layers, mantle and the crust.
The atmosphere (air), biosphere (living things), hydrosphere (water), and lithosphere (rock) are the four subsystems that flow matter and energy across their boundaries (land).
The ground formations we walk on, the inner layers, the mantle, and the crust all make up the lithosphere.
Different types of gases, such as oxygen, nitrogen, carbon dioxide, and various mixtures of gases, make up the atmosphere and are responsible for chemical functions.
The hydrosphere is made up of all of the planet's solid, gaseous, and liquid water.
Everything in the biosphere, from microbes to humans, is part of the biosphere.
