Earth's Past
100
The seafloor spreading theory was proposed by this man.
Who is Henry Hess?
100
A solid that is usually made of two or more minerals.
What is a rock?
100
Chemical weathering takes place fastest in these conditions.
What are hot and wet climates?
100
Earthquakes occur at this type of plate boundary.
What is a transform plate boundary?
100
Cavity in rock made when an organism decayed.
What is a mold?
200
As Earth's plates move apart at some boundaries, they collide at others, forming these.
What are mountains, volcanoes, and basins?
200
A mineral that contains something that can be useful and sold for profit.
What is an ore?
200
Soil formes rapidly in this climate.
What is tropical?
200
Type of plate collison that involves ssubduction and deep ocean trenches.
What are oceanic-oceanic collisions?
200
Principle that Earth's processes that occuring today are similar to those that occured in the past.
What is uniformitarianism?
300
The youngest rocks in the ocean floor are located at the mide-ocean blank.
What are ridges?
300
A diagram that shows the process of how rocks are changed from one type to another.
What is the rock cycle?
300
If a stream slows down, depositon will do this.
What is increase?
300
When one plate sinks under another plate.
What is subduction?
300
Process that uses the properties of atoms in rocks and other objects to determine their ages.
What is absolute dating?
400
The result of plate movement can be seen at here.
What are plate boundaries or rift valley's?
400
Igneous rocks that form below Earth's surface.
What are intrusive rocks?
400
Rich soil is often found under this area?
What are grassy lands?
400
Plate move apart, causing a mid-ocean ridge.
What are divergent plate boundaries?
400
States that in a sequence of undisturbed rocks, the oldest rocks are on the bottom and the rocks become progressively younger towards the top.
What is principle of superposition?
500
The presence of the same blank on several continents supports the idea of continental drift.
What are fossils and rocks?
500
Rocks with bands of minerals that have been heated and squeezed into parallel layers.
What are foliated rocks?
500
Mass movement is caused by this.
What is gravity?
500
Mountains made of huge, tilted blocks of rock seperated from surrounding rock by faults.
What are fault block mountains?
500
Method by which geologist can calculate the absolute age of the rock by knowing the half life of an isotope.
What is radiometric dating?
