map mysteries
A traveler walks north until reaching 90°N latitude. Where has the traveler arrived?
the north pole
Which ocean floor feature is the gently sloping underwater edge of a continent?
Continental shelf.
Tree roots grow into cracks in a rock and eventually split it apart. What caused the weathering?
Plant roots.
This landform is higher than the surrounding land and has steep sides.
mountain
True or False:
Longitude lines meet at the poles.
true
Two cities are located at 40°N latitude but have different longitudes. What does this tell you?
They are at the same distance north of the Equator but in different east-west locations.
A submarine leaves the continental shelf and suddenly begins descending steeply. What ocean feature has it entered?
Continental slope.
A statue near the ocean slowly becomes smoother over many years because of wind-blown sand. What type of weathering is occurring?
physical weathering
A family wants to build a farm on flat land that is easy to plow. Which landform would be most suitable?
plain
A student says, "The Equator is a line of longitude." Correct the mistake.
The Equator is a line of latitude.
You are standing at 0° latitude and 0° longitude. Which major imaginary line are you definitely standing on?
the Equator.
Scientists find a large, flat area deep in the ocean. Which feature are they describing?
Abyssal plain
A student says weathering always happens quickly. Is this statement correct? Explain.
No. Weathering usually happens very slowly over many years.
A student claims islands are found only in oceans. Is this always true?
No. Islands can also be found in lakes and rivers.
A map shows a volcano at 15°S, 60°E. Which coordinate tells how far south it is?
15°S latitude.
A map shows a mountain using a symbol that a student mistakes for a city. What map feature should the student have checked first?
the map key
Put these ocean features in order from shallowest to deepest:
A mountain becomes shorter and less jagged after thousands of years. Which process helped cause this change?
weathering
A plateau and a mountain are both elevated landforms. What is one major difference between them?
Plateaus have flat tops, while mountains have peaks.
You discover a deep-ocean feature after passing the continental rise. What is it most likely called?
Abyssal plain.
A ship sails from 20°N, 10°W to 20°N, 40°W. Did it travel mostly north-south or east-west? Explain.
East-west because the latitude stayed the same while longitude changed.
A fisherman notices that most fishing boats stay above the continental shelf instead of the abyssal plain. Why might this be true?
The continental shelf is shallower, receives more sunlight, and supports more marine life.

Valley.
