Front

What is the buoyant force acting on an object immersed in water?

Back

The buoyant force is equal to the weight of the water displaced by the object. For a 6kg object displacing 2kg of water, the buoyant force is 2kg.

Front

What is meant by Earth's water budget?

Back

Earth's water budget refers to the total amount of water contained in and on the planet, including oceans, rivers, lakes, and groundwater.

Front

Name two major types of submersibles.

Front

What are Remotely Operated Vehicles (ROVs)?

Back

ROVs are unoccupied, highly maneuverable underwater machines used to explore ocean depths while being operated from the water surface.

Front

What can be determined using specific latitude and longitude coordinates?

Back

The precise location of a geographical area.

Front

What principle explains the upward force experienced by an object submerged in a fluid?

Back

Archimedes' Principle states that the buoyant force on an object is equal to the weight of the fluid it displaces.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water evaporates, condenses, and precipitates, circulating through the atmosphere, land, and bodies of water.

Front

Define the term 'submersible'.

Back

Front

What is the significance of latitude and longitude in geography?

Back

Latitude and longitude are coordinates used to specify the precise location of any point on Earth's surface.

Front

What is the difference between a submarine and an ROV?

Back

A submarine is a manned vessel that can operate underwater, while an ROV is an unmanned vehicle controlled remotely.
