100
They are formed by nature not by humands
What four charcteristics do all minerals share?
100
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
100
The crust s 5 to 100km thick it is the thinnest kayer of earth
What are the characteristics of the crust
100
A block of lithosphere that xonsist of the crust and the rigid outer most part of the mantle
What is a tectonic plate
200
Luster streak cleavage fracture hardness density
When scientist are trying to identify a mineral they preform a series of test.
200
A sedimentary rock goes threw heat and preasure
Explain how to create a metamorphic rock
200
A muxh thicker layer than any other layer
What are the character of the mantle
200
The movement of continents that once formed pangea
What is the therary of continental drift? What was the name of the supercontinent
300
Diamond and corundom
Look at figure 5 on page 10 name 2 minerals that can scrath calcite.
300
A metamorphic rock melts into magma and then cools om to igneouse
Explain how to create a igneouse rock
300
The outer core is what covers the inner core in melted iron and nickel
What are the characteristics of the outer core
300
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
400
A naturally occuring solid mixture of one or more minerals or organic matter
What is a rock

Where is ocean floor new and were is it old
500
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
500
Has many other rocks comacted together
