Chapter one | Rock cycle | Section 1 | Layers |
---|---|---|---|
They are formed by nature not by humands
What four charcteristics do all minerals share?
|
A igneous rock goes threw weathering and erosion and turns inrocsediments and then goes threw compaction and cementation
Explain how to creat a sedimentary rock
|
The crust s 5 to 100km thick it is the thinnest kayer of earth
What are the characteristics of the crust
|
A block of lithosphere that xonsist of the crust and the rigid outer most part of the mantle
What is a tectonic plate
|
Luster streak cleavage fracture hardness density
When scientist are trying to identify a mineral they preform a series of test.
|
A sedimentary rock goes threw heat and preasure
Explain how to create a metamorphic rock
|
A muxh thicker layer than any other layer
What are the character of the mantle
|
The movement of continents that once formed pangea
What is the therary of continental drift? What was the name of the supercontinent
|
Diamond and corundom
Look at figure 5 on page 10 name 2 minerals that can scrath calcite.
|
A metamorphic rock melts into magma and then cools om to igneouse
Explain how to create a igneouse rock
|
The outer core is what covers the inner core in melted iron and nickel
What are the characteristics of the outer core
|
The mid-ocean ridge is were small underwater volcanos relece magma to form land
Explain the process of sea-floor spreading at a mid-ocean ridge
|
A naturally occuring solid mixture of one or more minerals or organic matter
What is a rock
|
Are finedgrained landmasses
What is the key feature of a sedimentary rock
|
The inner core is a solid iron ball
What are the charcateristics of the inner core
|
New ocean floor is closer to the ocean-ridgeand old ocean floor is neer the trench
Where is ocean floor new and were is it old
|
The series of procecces in which a rock forms changes from one typermto another is destroyed and forms again by heolical processes.
What is a rock cycle
|
Has many other rocks comacted together
What is a key feature of the metamorphic
|
1) lithoshpere 2) astenosphere 3) mesosphere 4)outer core 5) inner core
What are the 5 physical layers of the Earth
