What is profile drawing in geography?
A topographic profile is a diagram that shows the change of elevation of the land surface along a given line. The VERTICAL scale is the scale used to plot the elevation. It is usually larger than the horizontal or map scale, EXAGERATED, in order to emphasize the difference in the relief.
How must contour lines bend on a topographic map to indicate a stream valley How can you determine the which direction a stream would flow on a contour map?
Widely spaced contour lines indicate that the land is relatively level. A contour line that bends to form a V shape indicates a valley. The bend in the V points toward the higher end of the valley; this V points upstream, or in the direction from which the water flows, if there is a stream.
How does a contour map indicate areas of steep or gentle gradient?
From the contour map, a profile can be drawn of the terrain. Widely separated contour lines indicate a gentle slope. Contour lines that are very close together indicate a steep slope. The figure above illustrates various topographic features.
What does a steep slope look like on a topographic map?
Closely-spaced contour lines indicate a steep slope, because the elevation changes quickly in a small area. Contour lines that seem to touch indicate a very steep rise, like a cliff or canyon wall.
What are the topographic features?
Topographical Features Examples include mountains, hills, valleys, lakes, oceans, rivers, cities, dams, and roads. Elevation – The elevation, or height, of mountains and other objects is recorded as part of topography. It is usually recorded in reference to sea level (the surface of the ocean).
What is topography and example?
Topography is the study of the land surface. In particular, it lays the underlying foundation of a landscape. For example, topography refers to mountains, valleys, rivers, or craters on the surface. The narrow definition of topography is specific to the arrangement of landforms.
What are the three main types of topography?
Topography Types
- Karst Topography. Karst topography describes the distinct landscape that is made when underlying rocks dissolve or change shape.
- Mountain Topography. Topographical maps show landforms such as hills and mountains.
- Vegetation, Elevation and Glaciers.
What is the meaning of Topograpiya?
1a : the art or practice of graphic delineation in detail usually on maps or charts of natural and man-made features of a place or region especially in a way to show their relative positions and elevations. b : topographical surveying.
What is topographic effect?
The topographic effect is the variation in radiance from an inclined surface compared to the radiance from a horizontal surface as a function of the surface orientation relative to the light source and sensor position.
What is the importance of topography?
Importance of Topography As different landforms alter the climate of different places. Therefore it helps the weather forecasters to determine the weather conditions. Apart from this, the military uses this to gather information on the land area. Thus they can plan their strategies with the help of it.
How does topography affect climate?
The topography of an area can influence the weather and climate. Topography is the relief of an area. If an area is close to a body of water it tends to make milder climates. Mountainous areas tend to have more extreme weather because it acts as a barrier to air movements and moisture.
Is topography a science?
Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural and artificial features, and even local history and culture.
What is Earth’s topography?
Land topography is a digital image of the three-dimensional structure of the Earth’s surface. Shading indicates changes in slope or elevation. The relief shading in this topographic map comes mostly from elevation data collected by space-based radars.
Who studies topography?
A person who describes or maps the topography of a place or region. The definition of a topographer is someone who studies the surfaces of a land area and makes maps. An example of a topographer is someone working for the U.S. Geological Survey who creates and updates maps.
