Topographic Maps
A topographic map shows both __________ and _______________.
What is elevation and the shape of the land?
Pressure and heat cause magma to move up to the surface through weak spot's in the Earth's crust. Pressure builds until it looks for the nearest escape route.
What is, how magma escapes Earth's interior.
Four types of rapid changes that can alter landforms.
What are landslides, earthquakes, volcanoes, and floods?
Imaginary lines that follow the surface of a mountain at a precise elevation.
What are contour lines?
Layers of the Earth.
What are inner core, outer core, mantle, and crust?
Moves material from a high location to a low location very quickly.
What is a landslide?
The distance between two elevations on a topographic map.
What is a contour interval?
Signs that a dormant volcano may become active (at least 3).
What are hot soil, bubbling mud pots, and hot springs?
Flash flood occurring on July 31, 1976.
What is the Big Thompson Canyon Flood?
A side-view of a topographic map.
What is a profile?
Scientist use specific tools to attempt to predict volcanic eruptions.
What are tiltmeters to measure ground swelling, and seismographs to measure earthquakes?
This event can cause rock to rise of drop, and can trigger landslides.
What is an earthquake?
The steepness of a slope is determined by...
What is "How close together the contour lines are."
Active volcanoes provide...
What is new land, fertile soils, and ash and lava?
A specific fault type found deep in the Earth.
What is a blind thrust fault?
