Geologic Maps and Structures

The video tutorial introduces fossil collecting, focusing on trilobites, and explains how to locate them using geologic maps. It covers the history and elements of geologic maps, including legends, scale bars, and geographic coordinates. The tutorial also discusses terrain features, elevation, and geologic structures like folds and faults, providing a comprehensive guide to understanding and using geologic maps.

What type of environment did trilobites primarily inhabit?

• Mountains

• Forests

• Oceans

• Deserts

Who created the first large-scale geologic map?

• Alfred Wegener

• James Hutton

• William Smith

• Charles Darwin

What is the purpose of a legend on a geologic map?

• To provide a key to understanding map symbols

• To show the map's scale

• To indicate the map's title

• To display the map's creator

What do contour lines on a geologic map represent?

• Changes in vegetation

• Changes in rock type

• Changes in temperature

• Changes in elevation

What is the range of latitude values on a standard geographic coordinate system?

• -180 to 180 degrees

• -90 to 90 degrees

• 0 to 360 degrees

• -360 to 360 degrees

What does the strike and dip symbol on a geologic map indicate?

• The type of rock present

• The direction and angle of rock layers

• The elevation of the area

• The age of the rock formation

How are faults represented on geologic maps?

• As dotted lines

• As contour lines

• As thick lines separating different zones

• As color-coded areas

What type of fold has the oldest rocks at its core?

• Basin

• Syncline

• Anticline

• Dome

Which of the following is NOT a type of fold?

• Fault

• Anticline

• Basin

• Dome

What is the significance of angular unconformities on a geologic map?

• They indicate the presence of fossils

• They show different rock ages

• They reveal different strike and dip measurements

• They display elevation changes
