Skills – pg48

Due: Friday 29th Feb

No essay practice this week.

Homework for Week 5:

Learning Intention:

To be able to describe different climatic processes

Climatic Patterns and Processes

Climate… look at an atlas

Climatic Processes: heating of the earth

The sun heats the earth- Temperatures are warmer at the equator where the sun’s rays are more concentrated.How could the sun affect natural landscapes?

• Latitude: Generally the closer to the Equator the warmer the temperature. This is because light at the Equator hits at less of an angle than at the poles. Northland at 36°S has an average temp of 14°C, whereas at Tongariro at 39°S has an average temp of 7°C.

• Altitude: Saturated air cools at the rate of 0.6°C per 100 vertical metres.

• Relief: This can cause orographic rain (Rangipo Desert) and cause wind funnelling (e.g. Cook Strait).

Climate Controls copy

Climatic Processes: Aeolian ProcessesWind – occurs through the heating and

cooling of air. Air rises because it’s warm, then cools and falls. (convection current)

• How do you think wind could affect natural landscapes?

- Erosion (when something is warn away)

- Deposition – when particles are deposited somewhere)

Climatic Processes: Precipitation

Rain…Snow…Hail…Drizzle…

• How do you think precipitation could affect natural landscapes?

Erosion – rainfall wears away soils and rocks

Helps grow vegetationCreates flooding which erodes,

transports and deposits soil particles.

Precipitation: draw a simplified version

evaporation

Water condenses

Rainfall

This enters the rivers, glaciers, streams, lakes, ground water, oceans to complete the system

Simplified water cycle

Types of Rainfall: Orographic

Moist air forced to rise

Rain shadow on leeward side

Air warms as it descends

Air cools as it rises

Rain Dry

•Where could orographic rainfall occur in NZ?- West side of the mountain ranges•Where would the rain shadows be?- Eastern side of the mountain ranges•What does leeward mean?lee – shelterd areaLeeward – the sheltered side of something. Eg the Desert Road is the sheltered (leeward) side of Mt Ruapehu.
