M1,Q1: Characteristics of the Earth and Its Subsystems

Characteristics of the Earth and Its Subsystems

Characteristics of Earth that Sustain Life

Earth is unique. It is termed as “planet of life” where matter and energy continue to flow. Most of the cell’s processes requires energy from the Sun which is the main source of energy. Since Earth is a closed system, energy flows to all of its living components to continue various life processes and functions. The different forms of energy also allow the recycling of matter needed for life. What are the characteristics of Earth that make life possible? What makes Earth different from the rest of the planets and other heavenly bodies in the Solar System?

In this lesson, you are tasked to describe the characteristics of Earth that supports life.

Take a look at the pictures. Reflect on it. What do you see? Can you describe Earth’s characteristics through these illustrations?
