Plate Tectonics
How do scientists track the history of the plate movements ?
What is analyzing fossils and rock layers
Who created the continental drift theory?
Who is Alfred Wegener
The three types of plate movements
What is divergent, convergent, and transform
What is a Topographic Map?
What is a map that uses contour lines to show the shape of landforms at different elevations.
What are tectonic plates?
What is tectonic plates are pieces of land that connect together on the Earth's outer shell.
Who came up with the theory of seafloor spreading?
Who is Harry H. Hess
What is the most common plate boundary?
What is divergent boundary
If the lines are close on a topographic map what does that mean?
What is the path will be steeper.
How many major tectonic plates are there & name one?
What is seven & African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
what does Pangea mean?
what is all land
What is the most dangerous type of plate boundary?
What is at convergent plate boundaries
(where two continental plates collide earthquakes are deep and also very powerful.)
What kind of symbol is used to show the highest elevation?
What is a triangle with a circle in it OR a star
What are the seven crustal features?
What is volcanoes, mountain ranges, trenches, faults, volcanic island arcs, mid-ocean ridges, and rift valleys.
What were all the clues that supported the plate tectonic theory?
What is PUZZLE PIECES (the way the continents fit together), FOSSIL RECORDS (locations of fossils on continents that would have fit together), GEOLOGICAL RECORDS (nearly identical rock layers on continents that would have fit together), CLIMATE CHANGE (plants that live primarily in warmer regions found on multiple continents. )
How many inches do the plate boundaries move every year?
What is one to two inches per year
Who invented topographic maps?
Who is Charles Hutton
What is the smallest tectonic plate?
What is Juan de Fuca Plate
Where is the deepest part of the ocean?
What is the Mariana Trench
( It is formed by a convergent boundary between the Pacific Plate and the Mariana Plate. )
Which of the three plate boundaries are destructive and which are constructive?
What is divergent-constructive, convergent-destructive, & transform-construcvtive
When was the first topographic map drawn?
(Hint it was in B.C )
When was 2400 B.C.
