Chapter 3 Flashcards
What are the physical states of water?
Solid, liquid and gas.
What are water stores?
Water stores are places where water is contained and can be categorised as freshwater and saltwater stores.
What are oceans?
Oceans are large masses of water that are connected to one another.
What are the types of oceans?
Pacific Ocean, Atlantic Ocean, Indian Ocean, Arctic Ocean, and Southern Ocean.
What are glaciers?
Glaciers are large masses of ice that rest on land or float in the sea. They are found in places where it snows throughout the year so that enough snow accumulates and hardens into ice.
What are lakes?
Lakes are large bodies of water surrounded by land. They may receive water from rain, snow or rivers.
What are rivers?
Rivers are natural wide flows of freshwater across the land that store water temporarily before water flows into another water body. They flow from places of higher elevation to places of lower elevations as gravity pulls water downwards.
What is soil?
Soils refers to the loose topmost layer of the earth’s surface where plants grow. Soil has many very small openings known as pores for water to pass through when it rains, called soil moisture.
What is groundwater?
Groundwater is found below the surface of the Earth. Water enter the ground through pores in the soil due to gravity. Groundwater forms when a part of this water makes its way to the rocks beneath, filling up the pores and cracks of these rocks.

What is a water budget?
A water budget equation describe the flow of water in and out of a catchment area. Processes that increase the amount of water in a catchment are known as inputs while processes that decrease the amount of water in a catchment are known as outputs.

What is a water surplus?
When the input of water in a catchment is more than the output of water. More water is received than lost and the catchment is likely to have more than enough water available.
What is a water surplus?
When the input of water in a catchment is more than the output of water. More water is received than lost and the catchment is likely to have more than enough water available.
What is a water deficit?
When the output of water in a catchment is more than the inout of water. More water is lost than received and the catchment is likely to have less water available than is enough.
Types of inputs and outputs in a catchment?
Inputs: precipitation
Outputs: surface runoff, evaporation, transpiration and human use.
