Earth's 4 Spheres /4 Major Spheres of Earth

The video tutorial explains Earth's four major systems: geosphere, atmosphere, hydrosphere, and biosphere. It details the components and functions of each system and provides examples of how they interact. The geosphere includes the inner core, outer core, mantle, and crust. The atmosphere consists of five layers, including the ozone layer. The hydrosphere encompasses all water forms, while the biosphere includes all living organisms. The video highlights interactions such as volcanic eruptions affecting the atmosphere and hydrosphere, and how these systems support life on Earth.

Which part of the Geosphere is described as being smaller than the moon?

• The inner core

• The mantle

What is the primary function of the ozone layer in the Atmosphere?

• To support cloud formation

• To trap heat

• To provide oxygen

• To block radiation from the sun

Which of the following is NOT part of the Hydrosphere?

• Rivers

• Mountains

• Oceans

What role do plants play in the interaction between the Biosphere and Atmosphere?

• They absorb sunlight

• They release carbon dioxide

• They produce nitrogen

• They create oxygen

How do volcanic eruptions demonstrate the interaction between Earth's systems?

• They create new landforms

• They release particles into the atmosphere

• They increase ocean temperatures
