A winding mountain road is an example of a(n)?
A winding mountain road is an example of a curvilinear path, characterized by its non-straight, meandering shape. Such roads are designed to navigate the terrain's elevation changes and sharp angles, providing safer passage through steep or rugged landscapes. Additionally, they often enhance the scenic experience for drivers and passengers.
What are the advantages of a hovercraft?
The Advantages are that Hovercraft can fly, or more suitably, hover over water and land, can go over rough terrain and does not pollute as much as cars.
What is a shoulder heading?
A shoulder heading is a term used in civil engineering and construction to refer to a widened area at the side of a road or highway. It is typically designed to provide additional space for vehicles to pull over for emergencies or to accommodate stopped vehicles without obstructing traffic flow. Shoulder headings can also serve as a buffer zone between the road and adjacent obstacles or terrain.
Is hydraulic suspension better than telescopic?
I prefer mostly hydraulic suspension than telescopic suspension because they are suitable for both terrain and smooth roads than telescopic suspension. By G.Prithiv.
Why does the material for a hovercrafts skirt have to be flexible?
A flexible material allows excess air to escape and for the craft to maneuver over uneven terrain. Without a flexible skirt the craft would crash if it ran into an obstacle.
The difference in elevation between the highest and lowest parts of an area?
The difference in elevation between the highest and lowest points of an area is known as the relief. It is a measure of the variation in height within a specific region, often used to describe the topography or terrain of a landscape. High relief indicates steep slopes or large variations in elevation, while low relief suggests flatter terrain.
What is the principles of digital terrain modelling?
The principles of digital terrain modelling include elevation and local topographic variables. It also includes regional topographic variables as well as structural lines.
What tells the difference in elevation between two adjacent lines on a topographic map?
The contour lines on a topographic map represent the difference in elevation between two adjacent lines. The closer together the contour lines are, the steeper the terrain. If the lines are spaced far apart, it indicates a gentle slope. The contour interval, which is typically shown in the map's legend, specifies the difference in elevation between each contour line.
What is the difference between Ohio's terrain and Florida's terrain?

On a topographic map he difference in elevation between two side-by-side contour lines is called?
The difference in elevation between two side-by-side contour lines on a topographic map is called the contour interval. It represents the vertical distance between each contour line and helps depict the steepness of the terrain.
What is the difference between any two contour lines on a map?
Contour lines on a map represent points of equal elevation. The difference in elevation between any two contour lines is called the contour interval, which is usually indicated on the map legend. By knowing the contour interval, you can determine the steepness of the terrain in that specific area.
The difference between the highest point and the lowest point on the map?
The difference between the highest and lowest points on a map is known as the elevation range. It indicates the vertical distance between the highest and lowest elevation points on the map, providing insight into the topographical diversity of the area represented. This range is important for understanding the relief and terrain variations within the map area.
Where can I find a digital elevation map of Washington D.C.?
Google Maps now offers a 'Terrain' button. When you push this you get elevation and contour lines.The United States Geological Survey (USGS) has digital maps available for download. See the related links for the URL.
What is the difference between the highest and lowest point of an area called?
The difference between the highest and lowest points of an area is called the relief. It is a measure of the vertical elevation change within a defined region or landscape. Relief is often used to describe the topography or terrain of a particular area.
What is one difference between the blue ridge and Piedmont region?
One key difference is in their elevation: the Blue Ridge region is characterized by higher elevations and mountainous terrain, while the Piedmont region is characterized by lower elevations and rolling hills.
What is the change in elevation divide by distance?
The change in elevation divided by the distance traveled is known as the gradient or slope. It is commonly used to measure the steepness of inclines or declines along a route or terrain. The gradient is calculated by dividing the difference in elevation by the horizontal distance covered.
What types of maps show elevation of mountains?
Topographic maps display elevation of mountains through contour lines, which connect points of equal elevation. They provide a detailed representation of the terrain, including mountain peaks and valleys. Digital elevation models (DEM) are also used to create 3D visualizations of mountainous regions.
