---|---|---|---|---|
What are the four layers in the interior of the earth?
The crust, The mantle (upper and lower), the lithosphere, and the core.
|
What are the three types of rock?
Metamorphic (heat and pressure occurring to one rock then turning into metamorphic), Igneous (formed from magma or lava), and Sedimentary (rocks formed from sediments)
|
What is plate tectonics?
A theory that states pieces of the earth's surface move.
|
What are the three types of heat transfers?
Convection, Conduction, Radiation
|
What is mass?
The amount of matter in an object.
|
What is the asthenosphere?
A slushy zone of hot rock that has a small amount of melted rock.
|
What is chemical and physical weathering?
The breaking down of a rock that involves chemical reactions, and when physical forces break down rocks
|
What is seafloor spreading?
A hypothesis that states that new crust is formed at mid-ocean ridges.
|
Rises, Sinks
Warm air ___ and cool air ___.
|
What is density?
The mass of an object divided by the object's volume.
|
What is convection in the lower mantle?
The cooler denser rock falls to the bottom and the hotter less dense rock floats to the top.
|
What is graded bedding?
When rocks (large and small) settle at the bottom of a lake or river.
|
What is the three types of plates (seafloor spreading)?
lithospheric (pieces of the Earths lithosphere that move over the aesthenosphere), oceanic (thin, dense, lithospheric plates that are made of basalt and form the ocean floor), and continental (thick, less dense lithospheric plates that are made of granite and form the continents.)
|
What is convection?
The transfers of heat through liquids and gases.
|
What is a fluid?
Matter than can flow, usually liquid or gas.
|
What is original horizontally?
When sediments fall to the bottom of a body of water because of gravity, which causes layers in the rock.
|
What are things that can weather rocks?
Liquid water, frost wedging, glaciers, wind.
|
What is the three plate tectonic boundaries?
Divergent boundary (A lithospheric plate boundary where two plates move apart), convergent boundary (A lithospheric plate boundary where two plates come together), and transform fault boundary (A lithospheric plate boundary where two plates slide by each other.)
|
What is radiation?
The heat transfer that involves energy waves and no direct contact or movement by atoms
|
What is buoyant force?
An upward lifting force that acts as an object when it pushes aside a fluid.
|
What are cross-cutting relationships?
A theory that states the vein of a rock is the youngest of the different layers.
|
What is the rock cycle process?
A diagram that shows how one of the three main rocks can turn into other rocks.
|
What is a volcano being formed?
It is when oceanic crust subducts under the continental crust there are subduction zones. There is more activity in the subduction zones, causing volcanoes to form.
|
What is conduction?
The transfers of heat through direct contact of atoms and molecules.
|
No, because mass is the amount of matter in an object while weight is a measure of the pulling force of gravity on mass.
Is mass the same thing as weight? Explain.
