Alexis,

This assignment is incomplete. You scored 50 which is not passing. You need to complete the work and correct the ones you missed. Answers can be found in the lessons in the unit.
Complete and resubmit.

1.        James Hutton is considered the "father of geology":
A.        What theory did James Hutton develop? (2 points)
Ans. the rock cycle.

    2 points

 

B.        What is the main concept behind this theory? (3 points)

 

Ans. The rock cycle is a fundamental concept in geology that describes the dynamic transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous

    no credit

2.        Igneous rocks are often found along volcanoes and plate boundaries.
A.        What material do igneous rocks form from? (3 points)
Ans. Magma

     3 points

 

B.        What is the difference between the formation of intrusive and extrusive igneous rocks? (2 points)

Ans. Intrusive igneous rocks cooled below the surface of the planet, however, and generally display larger crystals due to the increased amount of time spent at mineral crystallization temperatures from the insulating effect of surrounding material.
     
Extrusive rocks are formed from magma at or above the surface of the planet, and generally display smaller mineral crystals, or no crystals at all, because of the rapid cooling environment in which they form. Chemically, an intrusive and extrusive rock could be identical, the only difference being the size of the mineral crystals they contain.

3.        What processes occur that change a sedimentary rock into an igneous rock? (4 points)

Ans. Sedimentary rock can be turned into lave or magma by contact with either of the substances or exposure to extreme heat. When the lave or magma cools, it becomes igneous rock.

  4 points

4.        What are three ways sedimentary rocks can form? (6 points)

Ans. Biologically, Chemically and Mechanically.

     no credit

5. What three factors can change a sedimentary rock into a metamorphic rock? (6 points)

Ans. heat,pressure,&chemically active fluids

     6 points

6.        Describe three actions caused by the force of water that help drive the rock cycle. (6 points)

Running water can (1) erode rock into smaller rock fragments, (2) dissolve rock into minerals, both of which can be redeposited as sedimentary rock, and (3) carried to the ocean to be melted at subducting plates.

7.        What processes found at a convergent boundary will help form the following rocks? (6 points)
A.        Metamorphic rocks
B.        Igneous rocks- Subduction process.
C.        Sedimentary rocks

    no credit

8.        What processes found at a divergent boundary will help form the following rocks? (6 points)
A.        Metamorphic rocks
B.        Igneous rocks
C.        Sedimentary rocks

no credit

 

9.        What event found at a transform boundary will help form metamorphic rocks? (2 points)

Ans. Metamorphic rocks form when rocks change after undergoing extreme pressure or temperature increase. These temperature changes must be hot enough to reorganize matter within the rock but not hot enough to melt it.

10.         What processes found at hot spots will help form the following rocks? (4 points)
A.        Metamorphic rocks
B.        Igneous rocks
