Topographic maps represent the locations of geographical features, such as hills and valleys Topographic maps use contour lines to show different elevations on a map A contour line is a type of isoline; in this case, a line of equal elevation If you walk along a contour line you will not go uphill or downhill
What term describes the difference in elevation between the highest and lowest parts of an area?
The elevation of an area is the difference in height between its highest and lowest point
Why is the contour interval included on a topographic map?
Why is the contour interval included on a topographic map? It tells you the change in elevation from line to line The mercator projection map shows Earth’s features on a grid
Which is not one of the main areas of earth science?
Test Question Answer 1st step in scientific inquiry? identify a problem Which of following is NOT one of the main areas of Earth Science? geology, oceanography, astrology, astronomy astrology area of earth science that examines the physical and biological changes that have occured in earth’s past historical geology
Which of the following is powered by energy from the earth’s interior?
Volcanic Eruption is powered by energy from Earth’s interior
Is the difference in elevation between the highest and lowest points on a map?
The difference in elevation between the highest and lowest contour lines on a topographical map is called contour interval
What term is used to describe the difference in elevation?
What term describes the difference in elevation between the highest and lowest parts of an area? elevation
What does an elevation map show?
Answer and Explanation: An elevation map shows the height of physical parts of the Earth, relative to sea level
What is the difference in elevation between index contours?
The elevation difference between two adjacent contour lines is called the contour interval (CI) Usually the contour interval is noted on the map legend In most topographic maps every 5th contour line is drawn in bold print or wider than other contours Therefore the contour interval is 20 meters
What are the 4 major spheres of Earth?
Everything in Earth’s system can be placed into one of four major subsystems: land, water, living things, or air These four subsystems are called “spheres” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air)
Can theories be revised?
Accepted theories may be modified or overturned as new evidence and perspective emerges Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more
Are fish part of the biosphere?
Bio means “life” The biosphere is made up of all the living things on Earth and it includes fish, birds, plants, and even people
Which is caused by the sun’s energy?
The sun generates energy from a process called nuclear fusion During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons Hydrogen nuclei fuse to form one helium atom The sun provides more energy in an hour than the United States can use in a year!
How is energy from volcanoes and interior of earth?
Earth’s interior has a great amount of heat energy During a volcano eruption, the heat energy is transferred through lava to the surface of Earth Magma which becomes trapped below the surface can build up pressure that must be released as mechanical energy
Which is a renewable source of energy?
Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy Biomass refers to organic material from plants or animals This includes wood, sewage, and ethanol (which comes from corn or other plants)
What is the difference between the highest and lowest points on earth?
An area’s highest point is defined as the point with the highest elevation above sea level It can be a peak, summit, or raised surface On the other hand, the lowest point is the lowest elevation below the sea level
What is the difference in elevation between one contour line and the next?
Each contour line represents a specific elevation and connects all the points that are at the same elevation Two contour lines next to one another are separated by a constant difference in elevation (such as 20 ft or 100 ft) This difference between contour lines is called the contour interval
What is the difference between elevation and relief?
The elevation of an object is it’s height above sea level Relief is the difference in height elevation between geographic features
What type of map shows areas of high and low elevation?
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)
What term is used to refer to the differences in elevation on a map?
In cartography, a contour line (often just called a “contour”) joins points of equal elevation (height) above a given level, such as mean sea level The contour interval of a contour map is the difference in elevation between successive contour lines
What is the term used to describe elevations on maps?
They can be shown on maps by contour lines, which connect points with the same elevation; by bands of color; or by numbers giving the exact elevations of particular points on the Earths surface Maps that show elevations are called topographic maps Elevation influences climate, as well as where and how people live
What is elevation difference?
The vertical distance between two points is called the difference in elevation , which is similar to what you have learned as the difference in height (see Section 50) The process of measuring differences in elevation is called levelling , and is a basic operation in topographical surveys
What kind of map shows elevation in its legend?
The elevation as a legend will most likely be found in the physical map Thus, the answer is letter C The physical map often times includes the data such as those in political map
What are the different types of topographic maps?
Because topographic maps are usually associated with elevation data they are sometimes referred to as terrain maps, elevation maps, altitude maps, contour maps Elevation data for these types of maps can be collected via a variety of different devices
How do you find the elevation on a topographic map?
You can figure out the elevation of any point by finding the nearest labeled line, counting the number of lines above or below it, multiplying by the contour interval, and adding or subtracting the result from the nearest marked contour line The more closely spaced the contour lines, the steeper the slope
How do the contours differ between a steep slope and a shallow slope?
Closely-spaced contour lines indicate a steep slope, because elevation changes quickly in a small area In contrast, broadly spaced contour lines indicate a shallow slope Contour lines that seem to touch indicate a very steep or vertical rise, like a cliff or canyon wall
How do you determine elevation?
Measuring elevation requires a series of complicated measurements Most scientists today measure the elevation of mountains by placing radios on the peaks of a mountain range, after which, satellites take measurements and determine the elevation
What is the highest contour line represented on the map?
Index lines are the thickest contour lines and are usually labeled with a number at one point along the line This tells you the elevation above sea level
What is the elevation of point C?
The elevation of point C is 1,500 miles The highest point or peak of a mountain top
