§3.1: water in motion

Today

• Explanation §3.1
• Worksheet 'hydrological cycle'

Learning goals

• You know how the short and long hydrological cycles work 
  
• You know in which forms water is stored

Vocabulary 

Condensation	Condensatie	The process of gas turning into a liquid
Evaporation	Verdamping	The process of a liquid turning into a gas
Water vapor	Waterdamp	Water in its invisible gaseous form
Precipitation	Neerslag	Water in any form, rain, snow or hail, falling to the ground
Surface runoff	Oppervlakte-afvoer	Water flowing into rivers or lakes because there is more water than the land can absorb
Transpiration	Transpiratie	The evaporation of water vapor by plants or by vegetation
Infiltration	Infiltratie	Process by which water on the ground enters the soil

Which three states of water exist?

Water

• Solid
• Liquid
• Gas

Gaseous state of water (water vapor) is invisible 

Water

Water

SOLID	LIQUID	GAS
ice	water	water vapor
glaciers	Oceans Rivers Lakes	in the air (invisible)

Hydrological cycle

The process by which seawater returns to the sea through evaporation (verdamping) and precipitation (neerslag) and through ground water and rivers.

• Short hydrological cycle (korte waterkringloop)
• Long hydrological cycle (lange waterkringloop)

Short hydrological cycle

1. Sea water evaporates 
2. Condensation 


3. Precipitation in the same sea or ocean
4. Collection

Long hydrological cycle

Surface runoff

Condensation

Evaporation

Precipitation

Long hydrological cycle

Condensation

Evaporation

Precipitation

Surface runoff 

Hydrological cycle

Where do you see:

• Short hydrological cycle
  
• Long hydrological cycle
  

Explain the difference between:

• Rain river
  
• Meltwater river
  
• Mixed river
  

Explain the difference between the short and the long hydrological cycle
