Earth's Systems - geosphere & hydrosphere

What is the objective of learning about Earth's systems as mentioned in the document?

• To understand the composition of Earth's atmosphere

• To learn how matter moves within and between Earth's 4 spheres

• To study the effects of human activity on Earth's climate

• To explore the different types of rocks on Earth's surface

What is the definition of 'Density' as provided in the document?

• The amount of heat in a certain volume of matter

• The amount of air in a certain volume of matter

• The property of matter that is equal to the amount of mass in a certain volume of matter

• The amount of water in a certain volume of matter

What is convection in the context of Earth's geology?

• The process by which water cycles through the Earth's atmosphere

• The transfer of energy caused by the circulation of matter due to different densities

• The movement of tectonic plates beneath the Earth's surface

• The solidification of magma as it cools and becomes part of the Earth's crust

What causes the mantle to "move" according to the text?

• The rotation of the Earth on its axis

• The gravitational pull of the moon

• The circulation of matter due to different densities

• The force of gravity pulling all material toward the center of the Earth
