What is latitude?
a zone of climate and vegetation
an indication of how far north or south a point is
a division between hemispheres
an imaginary line that bisects the globe
Latitude is an indication of how far north or south a point is on the Earth's surface. It is measured as angular distance in degrees, minutes, and seconds from the Equator, which is assigned a latitude of 0 degrees. The latitude lines, also known as parallels, are imaginary circles that run east-west around the globe and help in locating places on Earth.
How is a location defined in the system of latitude and longitude?
with a single numeric value
with a unique satellite tag
with a pair of coordinates
with a negative number
A location is defined in the system of latitude and longitude with a pair of coordinates. These coordinates consist of a numeric value for both latitude and longitude. Latitude is measured in degrees, minutes, and seconds, indicating the distance north or south of the Equator. Longitude is also measured in degrees, minutes, and seconds, indicating the distance east or west of the Prime Meridian (which passes through Greenwich, England). By combining the latitude and longitude coordinates, a specific location on Earth can be identified.
Which of the following offers the best comparison between maps and globes?
1.) Globes present the exact size of objects on Earth, but maps do not.
2.) Map projections more accurately present locations on Earth than globe projections do.
3.) Maps do not distort the location of objects on Earth, but globes do.
4.) Globes re-create the spherical shape of Earth, while maps distort some aspects of it to present it on a flat surface.
The best comparison between maps and globes is:
4.) Globes re-create the spherical shape of Earth, while maps distort some aspects of it to present it on a flat surface.
While globes accurately represent the spherical shape of the Earth, maps need to use various projections to flatten the surface of the Earth onto a two-dimensional plane. This flattening process inevitably introduces distortions in certain aspects of the map, such as distances, sizes, and shapes of objects.
In which situation would a Mercator projection map be most useful? A.) when comparing the size of Canada to the size of Mexico B.) when traveling from Florida to Texas C.) when tracking weather patterns along the East Coast D.) when navigating a ship across the Atlantic Ocean
A Mercator projection map would be most useful in option D) when navigating a ship across the Atlantic Ocean.
The Mercator projection is a cylindrical map projection that preserves directional accuracy, making it ideal for navigation purposes. It represents lines of constant compass bearing as straight lines, which helps to plot a constant course while traveling across the ocean. This projection is commonly used in maritime navigation due to its usefulness in representing large areas accurately for navigation purposes, especially along east-west routes like the Atlantic Ocean.
What type of map might a hiker exploring different levels of elevation in the Rocky Mountains find to be the most helpful?
A.) Topographic map
B.) Navigation chart
C.) General reference map
D.) Thematic map
The type of map that a hiker exploring different levels of elevation in the Rocky Mountains would find most helpful is A) Topographic map.
A topographic map provides detailed information about the elevation and terrain features of an area. It uses contour lines to show changes in elevation, allowing hikers to understand the slope, steepness, and relief of the land. This is particularly valuable for hikers in mountainous regions like the Rocky Mountains, where the terrain is rugged and elevation changes significantly.
A topographic map also includes other important details essential for hikers, such as trails, rivers, lakes, and landmarks. It allows hikers to plan their routes, assess the difficulty of the terrain, identify potential hazards or obstacles, and locate landmarks for navigation.
Is the Mercator projection useful?
A.) No; latitude/longitude lines aren't needed with GPS
B.) No; its distortions are too great
C.) Yes; when creating thematic maps
D.) Yes; in naval settings without roads
