Skills – pg48
Due: Friday 29th Feb
No essay practice this week.
Homework for Week 5:
Learning Intention:
To be able to describe how different landforms are created
Climatic Patterns and Processes
How are these natural features created?
Task:
Listen to the natural process described so you can re-write it in your own words and provide a labelled diagram.
Tectonic ProcessesEarth’s crust covers the globe – even under the ocean.
The earth’s crust sits on top of the mantle which is full of hot liquid magma. The magma is heated when close to the core and then cools as it heads towards the surface. As the magma rises it cools and therefore heads towards the surface again. This is process is called convection currents.
• Write down any questions that you have from today’s lesson.
• In your groups, work out the question you can’t answer.
Learning Intention:
To be able to describe how different landforms are created
• What are tectonic processes? Answer: Tectonic processes are the processes that move the earth’s crust. They involve convection currents, continental drift, earthquakes, volcanic eruption. Tectonic processes is a theory that suggests that the earth’s crust is divided up into sections and the convections currents cause the tectonic plates to move in different directions, creating different plate boundary movements eg. Diverging, converging, lateral/transform boundaries.
•Why is the PACIFIC plate subducting in a different direction to other plates eg the NAZCA plate?Answer: Plates move according to the convection currents – so where some move east, others will move north. Around NZ the Pacific plate is moving to the West and subducts under the Australsia plate. However the NAZCA plate moves to the east thus creating a diverging boundary along the NAZCA/PACIFIC intersection. The NAZCA plate then subducts under the SOUTH AMERICAN plate – toward the West – the opposite to the subduction direction of the PACIFIC plate.
