Study Notes
Introduction to Earth Systems - Surface Features in the Geosphere
- This lesson covers surface features in the geosphere, including topography, landforms and Earth-shaping forces, using mapping tools
- Objectives include understanding topography and landforms, exploring Earth-shaping forces, and utilizing mapping tools
- Topography describes the shape of the land using elevation, relief, and landforms
- Elevation is the height above sea level
- Relief is the difference in elevation between the highest and lowest points in an area
- Landforms are features like mountains, plateaus, dunes, and rivers
- Different landforms have different combinations of elevations and relief
Constructive Forces
- Constructive forces create or build landforms by adding material to the Earth's surface
- Examples of these forces:
- Mountain formation like the Himalayas, formed by colliding tectonic plates
- Creation of new landmasses by volcanic activity
Destructive Forces
- Destructive forces break down or erode landforms, reducing elevation
- Examples of these forces:
- Erosion of rocks due to factors such as rain, wind, ice, and temperature changes
- Natural events like landslides, earthquakes, and volcanic eruptions. These can release ashes into the atmosphere, affecting the living organisms
Modeling Landforms
- Modern mapping uses computers, aerial photos, and satellite images to create maps showing land features
- Topographic Maps use contour lines to show elevation by connecting points at the same height
Topographic Maps
- Contour lines in a topographic map show the shape of a landform (elevation)
- Contour intervals represent the change in elevation between contour lines
- Features like ridges, valleys, and depressions can be identified using the shape of contour lines
- Hilltops are shown as closed contour loops
- Steep slopes are marked with closely spaced contour lines
- Flat areas are marked by widely spaced contour lines
Aerial Photography
- Aerial photography uses photos taken from airplanes to capture detailed images of a large area
- Photographs are pieced together to create a detailed image of a large area
Satellite Imagery
- Satellites collect and store data about the Earth's surface
- Computers process this data creating satellite images with features such as plants, land, water, snow, and ice
Global Positioning System (GPS) and Geographic Information Systems (GIS)
- Global Positioning System (GPS) uses satellites signals to determine a location
- Geographic Information System (GIS) combines data, and helps solve problems like flood risk analysis
- Both GPS and GIS are more useful than topographic maps because they provide more information about the terrain by combining multiple data sources allowing a more detailed analysis and precise locations.
Measurements and Interpretations
- Mapping tools and data help to precisely understand shapes, elevations, and landforms, assisting in critical analysis of given datasets
