Unit 5 Where Does All The Water Go? *Clean out notebook of Unit 4 materials and put aside for the MIDTERM FEB 5, 2025  Today’s Objective: What is a Landscape Region? Landscape – a region on Earth’s surface in which landforms have a common origin. Topography – Shows the shape of the land (highlights various landscape regions) Relief – The change in elevation There are three major landscape regions, they are classified based on their BEDROCK and ELEVATION  Mountains Greatest relief Peaks & Valleys Non-horizontal bedrock Usually metamorphic rock  How are they different? Plateaus Medium relief Catskills Several stream valleys Dissected Plateau Flat bedrock structure Sedimentary Bedrock Usually sedimentary rock Adirondacks True Mountains Metamorphic Bedrock  How does climate influence landscapes? The amount and distribution of Plains precipitation influence measurable landscape characteristics. Little relief Low elevation Flat Dry Wet ARID (dry) climates generally have – thin soils with little humus – sharp angles and steep slopes. ARID Landscape Regions Landscapes in MOIST climates generally have - thick rich soil - smooth and rounded features HUMID Landscape Region  Softer rock erodes faster than harder, durable rock. The more durable layers will form the steepest slopes or cliffs Durable rock form higher portions of a landscape – plateaus , mountains, and cliffs  Drainage Patterns The way water flows off the landscape depends on the bedrock structure Drainage patterns are determined Think about pouring by the way small streams, or water over a landscape region, how would the TRIBUTARIES join larger water travel? streams. Radial Dendtritic (branching) Mountainous areas Plains – Very flat areas Water flows in all directions Water branches together Trellis (rectangular) Annular Plateaus Forms when an igneous intrusion Folded or faulted bedrock is exposed at the surface  Drainage Basin (watershed) All the water that drains off of a landscape region into a body of water (ocean or stream)  Notes packet pg 4 Color the regions inside New York to match the landscape regions Mountains Plateaus Plains  Notes packet pg 5 Using the same colors, color the regions inside New York to match the landscape regions Mountains Plateaus Plains
