It's a solid, non living, formed in nature and has a crystalline structure.
What 4 characteristics do all minerals have?
|
A mixture of two or more minerals.
What is a rock?
|
Has two parts oceanic and continental. It is broken up into plates.
What are the characteristics of the crust?
|
Pieces of the lithosphere that move around on top of the asthenosphere that fit together like a puzzle piece.
What is a tectonic plate?
|
A convergent boundary.
What boundary creates a mountain?
|
|
Color, luster, hardness, streak, composition, texture, and cleavage and fracture.
When scientist are trying to identify a mineral they perform a series of test. List 7 different tests that can be preformed in identifying minerals?
|
The continual process by which new rocks form from rock material.
What is the rock cycle?
|
Has three parts. The lithosphere which is the solid upper part of the mantle that carries the tectonic plates, the asthenosphere and mesosphere is the strong lower part. It's most of Earths mass 67%.
What are the characteristics of the mantle?
|
It's a hypothesis made by Alfred Wegner that states the the continents once formed a Single landmass called Pangaea.
What is the theory of continental drift?
|
A divergent boundary
What boundary creates a mid ocean ridge?
|
|
Diamond and Quartz.
Name 2 minerals that can scratch calcite?
|
Any rock weathers down into sediments then later compacts and cements into sedimentary rock.
How do you create a sedimentary rock?
|
It is very hot and a liquid layer surrounding the inner core. Made mostly of iron and nickel.
What are the characteristics of the outer core?
|
New oceanic lithosphere forms as magma rises towards the surface of the Earth and solidifies.
Explain the process of sea floor spreading at a mid ocean ridge?
|
A transform boundary
What boundary creates a fault?
|
|
Softest- talc and Hardest- Diamond
What is the hardest and softest mineral and MOHs hardness scale?
|
Any rock heat and pressure to form a metamorphic rock.
How do you create a metamorphic rock?
|
The inner core is a dense ball of solid iron that reaches temperatures of 11,000 degrees. It's the very inside of the Earth.
What are the characteristics of the inner core?
|
It's newest by mid ocean ridges and oldest by trenches.
Where is the ocean floor new and old?
|
Divergent boundary
Does a divergent or convergent boundary create a volcano?
|
|
Cleavage is the splitting of a mineral along smooth flat surface and fracture is the manner of a mineral breaks along a curve or irregular surface.
What is the difference between cleavage and fracture?
|
Can be foliated has a pattern design and non foliated which has no pattern.
What are the key features of a metamorphic rock?
|
Lithosphere, Asthenosphere, Mesosphere, outer core and inner core.
What are the 5 physical layers of the Earth?
|
Sea floor spreading.
What is the process called when new ocean floor is being created?
|
Any change in shape in a rock do to stress
What is deformation?
