1. WHAT IS THE HYDROSPHERE?
• Earth’s surface waters.
WHY DO WE LOOK AT THE HYDROSPHERE?
• Water is one of the most important resources on the planet.
• Unevenly distributed but crucial resource.
• Water also has the power to shape the landscape over long periods of time / shorter bursts of activity.
• Water is life-giving and life-threatening.
Key words: HydrosphereHydrology: the scientific study of the water at the earth’s
surface and its links with the atmosphere.
Hydrosphere: the Earth’s surface waters.
Hydrological cycle: global distribution and movement of water between the oceans, the atmosphere, vegetation and the land.
Closed system: the total amount of water is the same, with virtually no water added or lost from the cycle. Water just moves from one storage type to another.
HYDROSPHERE
Starting Point:
a. Earth’s Water.b. Distribution of fresh and salt water.

THE GLOBAL HYDROLOGICAL CYCLE
Moist air moves upwards, begins to cool and
condense
Precipitation returns waterto the Earth’s surface.
Most water runs off the surfacebut some percolates through the
soil and travels underground to seas and oceans
Water converted into vapour by evaporation
and transpiration
Activity 3: Annotation
TASK:Using the information on page
44+45 section 3.1, annotate the following key words.
1.Evaporation2.Transpiration3.Condensation4.Precipitation5.Infiltration
6.Throughflow7.Percolation
8.Groundwater9.Surface runoff
SUCCESS CRITERIA:
You MUST add extra description and explanation to
each of the key words.
You SHOULD highlight (use a key), which key words are:
•INPUTS•STORAGE
•TRANSFERS•OUTPUTS
You COULD write a short explanation of how
atmosphere and hydrosphere are related.

Homework: THE GLOBAL HYDROLOGICAL CYCLE
Copy fig 3.2 p. 39 and using page 38 39:
Describe the global hydrological cycle (6-10 marks)
With a diagram this question is usually worth between 6 and 10 marks
– The Earth contains a finite amount of water – The highest % is stored in the world’s oceans (95%)– Second highest % trapped in ice caps and at the poles– Heat from sun results in evaporation from the oceans– Moist air condenses and precipitation results– Clouds form and transport water– Precipitation may occur as rain or snow depending on altitude– Rainwater returns to oceans and seas via rivers and streams– Water can infiltrate the soil and rocks and return to the system
as groundwater flow– Water can also be evaporated from lakes or transpired from
vegetation
