L1: Intro to Module

Question 1

What is alpine tundra?

Answer 1

Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation.

Question 2

What can be used to model the alpine zone?

Answer 2

Energy flow

Many tundra areas have very low energy availability/ output

Question 3

What processes characterise the alpine zone?

Answer 3

Concentrated processes

Concentrated weathering -> + energy -> serrated landscape (sharp edges, high relief, sharp relief)

Axial glaciers/ rivers/ flows -> incision -> secondary slopes

Axial deposition forms ornament the landscape.

Question 4

What processes characterise the arctic meso-scale mesoscale (less than 100km)?

Answer 4

Diffused processes

Tectonics/ geology -> low relief -> no axial process

Slow slope transport -> deep weathering -> masks geology

Minimal production of axial deposition

Question 5

What is arctic landscape like?

Answer 5

Flat/ low relief

Slow slope transport

Tundra/ vegetation/ mosses

Weathered material- deep layer of deposits (ancient)

Question 6

…in both areas =

Answer 6

Treeless
