Why is topography important to farming?
Topography is the dominant factor in controlling the flow and accumulation of water, organic matter, and other material in landscapes, which in turn affects the development and properties of soils. Topography influences the removal and deposition of soil materials by water, wind, and tillage practices.
What is topography in agriculture?
Topography—that is, the surface of the soil and its relation to other areas—influences efficiency of operation. In modern mechanized farming, large, relatively level fields allow for lower operating costs.
How do you identify a topographic map?
The shape of the contour lines is an important piece of information that allows you to identify features on the map such as peaks, ridges, passes or valleys. Smaller circular shapes are most likely showing you peaks or hills, whereas V-shapes are probably showing you a spur or ridge.
What information can be found on a topographic map?
Topographic maps are a detailed record of a land area, giving geographic positions and elevations for both natural and man-made features. They show the shape of the land the mountains, valleys, and plains by means of brown contour lines (lines of equal elevation above sea level).
How does topography affect a site?
Topography is an important factor in site analysis. If a site is flat, topography will not affect the location and layout of the building. But on a sloping site topography is a significant factor. The slope of a site or slope of an adjacent site will affect the access of sun & views.
What type of farming uses the topography of the land to slow water flow?
Contour farming, the practice of tilling sloped land along lines of consistent elevation in order to conserve rainwater and to reduce soil losses from surface erosion.
What are examples of topography?
What are examples of topography? 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 the topography. It is usually recorded in reference to sea level (the surface of the ocean).
What are the 5 colors on a map?
RED -Overprinted on primary and secondary roads to highlight them.
What are the symbols on a topographic map?
Topographic Map Legend and Symbols
- Brown lines – contours (note that intervals vary)
- Black lines – roads, railroads, trails, and boundaries.
- Red lines – survey lines (township, range, and section lines)
- Blue areas – streams and solid is for larger bodies of water.
- Green areas – vegetation, typically trees or dense foliage.
What are some topographical 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).
How important is the topography of a site affects the production?
Field Topography – Poorly drained fields or those with low areas can become water logged during periods of excessive rain. Such conditions can enhance the incidence of diseases, reduce plant vigor and yield, and, under excessive conditions, cause plant death.
What are the three main types of topography?
- 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 are the features shown on a topographic map?
Topographic map. –A topographic map, as distinguished from other kinds, portrays by some means the shape and elevation of the ter rain. Geological Survey topographic maps usu ally represent elevations and laNdforms–the shapes into which the earth’s surface is sculp tured by natural forces–by contour lines.
How does the topography of an area affect agriculture?
The topography of an area intended for agricultural purposes is an important consideration as the positioning of agricultural fields with respect to… See full answer below. Our experts can answer your tough homework and study questions.
How are Canadian topographic maps made to scale?
Maps are made to scale. In each case, the scale represents the ratio of a distance on the map to the actual distance on the ground. A standard Canadian topographic map is produced at 1:50 000, where 2 cm on the map represents 1 km on the ground. Medium-scale maps (e.g. 1:50 000) cover smaller areas in greater detail, whereas small-scale maps
Where are the coordinates on a topographic map?
The coordinate value for each grid line can be found along the edge of the map. Northing values can be read along the east or west edges of the map and easting values can be read along the north or south edges of the map.
