Desert landforms – importance of water? Erosion and deposition. Earth movements? Key Idea 1: Different forces shaping landforms.
Changing processes as (desert) climate changes. Landform modification occurs
Landforms of glacial erosion – upland Impressive features if rocks resistant
Pre-existing landforms? Weathering? Transport? Erosion?
Features of a Glacial lowland – deposition. See pre and post glacial structures and altered landforms!
Coastal erosion Time: headland to cave to arch to stack.
Longshore drift Depositional feature – a spit Importance of wind and waves
Glaciation meets coasts Glaciers erode below base level (out to sea) Sea level rises after ice melts
Post glacial uplift Isostatic recovery
FEATURES OF EROSION & FEATURES OF DEPOSITION RIVERS.

Wave Erosion 16.2 Review. Headlands Resistant rock left that projects into the ocean Typically granites or very very resitant sandstone.
The Coastal System. Coasts can be studied in several different ways dependent upon their classification: Erosional or depositional Sediment type (clastic:
High Energy Events And longer intervening periods of relative stability How do they influence the evolution of glaciated landscapes?

WS 7.1, Page 21 1a) Strength of wind and fetch affect the size of waves. The stronger to wind, the larger the size of waves. The longer the distance over.
What is a rock?. A rock is a naturally occurring solid mixture of one or more minerals or organic matter.
Glacial Erosion What route does a glacier follow?.

Wave Dominated Coasts Objective: to examine some of the processes and characteristics active on a wave-dominated coast.
Agents of Erosion. Erosion The process by which water, ice, wind or gravity moves fragments of rock and soil.
Changes to the Earth’s Surface Grade 5 Science. Landforms Landforms are the physical features on the Earth’s surface such as, valleys, rivers, mountains,
1 What happened in the Ice Age. 2 At present about 10% of the Earth's surface is ice covered, but about two million years ago the Planet's climate became.
CH 16 The Dynamic Ocean Ocean water is in constant motion and powered by many forces Forces include wind, Coriolis, gravity, density differences Ocean.

GEOGRAPHY LABELLING A FIELD SKETCH YEAR 10 GEOGRAPHY LABELLING A FIELD SKETCH GCSE- HIGHER GRADE.
Corrie, cirque, cwm – hollow where a glacier formed Armchair shaped hollow – usually northerly aspect in UK and N. Hemisphere. Steep back wall e.g. Llyn.
1 COASTS. 2 What processes make coasts change shape? Erosion attrition abrasion corrosion hydraulic action Deposition traction saltation suspension solution.
The Water Cycle. Processes in the Water Cycle The water cycle is made up of 5 processes The water cycle is made up of 5 processes –Evaporation/transpiration-
1) What are the main geomorphological processes shaping landforms in an area undergoing active glaciation? 2) Show how one named landform has been shaped.
GLACIERS In the following presentation you are going to see some actual pictures of glaciers and landforms resulting from glacial movement. Some key words.
