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.

Earth's Water and the Hydrologic Cycle

What is the hydrological cycle and how does it function?

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 2: Map from memory

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
