Which of the following best describes why some identical animal fossils have been discovered on opposite sides of the ocean?
Fossils over time, do fossilize into the same structures.
In the beginning, animals were close if not identical in different parts of the world.
The continents were one once large land mass.
As animals and people traveled for food, they took them there.
Name two things that support continental drift?
The seafloor is spreading.
Ice is melting from global warming at alarming rates
Volcanoes form islands.
Earthquakes make land mass drift off into the ocean.
The Earth's surface is slowly and constantly changing.
Check all that are true statements.
Divergent Plate boundaries cause a line of earthquakes and lines of volcanoes.
Movement of plate tectonics causing fault lines.
Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
The theory of continental drift is most associated with the scientist Alfred Wegener.
Identical rock types, identical fossils, and very similar mountain ranges are found on different continents that are separated by a wide ocean. Which of these best explains these observations?
Ice covered most of the oceans, making land travel easy.
Animals were more aquatic and could all swim in the beginning of earth.
Pangea
Rock formations are the same when earth was formed and evolved over time.
A divergent boundary can cause or be caused by:
Create a new sea floor
A rift valley in a sea can get larger.
Two plates move away from each other
An underwater volcano is formed
The process of moving sediments by water or wind in the rock cycle.
compaction
crystallization
deposition
deformation
Weathering and erosion most likely cause what type of rock?
granite
metamorphic
sedimentary
igneous
Earthquakes in Calfornia are most likely caused from
The massive amount of Hollywood mansions
One oceanic plate moving beneath another oceanic plate at a trench
Ocean salt level
Two plates running into each other.
In order to find a rock or mineral in a particular location, what would be the first thing you might do as a scientist?
Look at what locations have had that rock or mineral found recently?
Google what natural disasters have factored into sediment distribution.
Conduct an experiment on the rock/mineral and see if it is flamable.
Find another local scientist interested in the same ideas.
