Question

HELP

Answer 1

1. Igneous Rock:

How is igneous rock formed?
What is the specific name for the rock formed when lava cools and hardens at the earth’s surface?
What is the specific name for the rock formed when magma cools and hardens below the earth’s surface?
How does crystal size compare in extrusive vs. intrusive rock? Explain the cause of this difference.
Give one example of extrusive igneous rock and one example of intrusive igneous rock shown in the video.
2. Sedimentary Rock:

How is sedimentary rock formed?
What is the name of an impression formed when tiny plants or animals become trapped between sediment layers?
List three examples of sedimentary rock shown in the video, add any notes about each rock’s properties that you observed:
3. Metamorphic Rock:

How is metamorphic rock formed?
What are two examples of heat or pressure that can form metamorphic rock?
Identify the type of metamorphic rock that can be formed when each of the following is exposed to heat or pressure:
Limestone:
Sandstone:
Shale:
Granite:
Part II - Rock Identification Activity
Instructions: Fill in the chart and answer the questions below in complete sentences.

Fill in the chart based on the characteristics you observe in each rock sample on the lesson page, and use those observations to help you identify the type of rock. The example shows how to fill in the information for a non-foliated rock with a coarse texture and no fossils.
Sample Foliation Intrusive/ Extrusive Fossils Texture Metamorphic/ Sedimentary/ Igneous Name of Rock
Example No Extrusive No Coarse Igneous Diorite

Answer 4

Igneous Rock Is Formed Thru The Cooling Of Lava

Answer 5

ig i'll do 2

Answer 6

When Magma And Lava Cools, It Forms Plutonic Rocks.

Answer 7

Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area

Answer 8

When magma takes a long time to cool, it has time to develop big crystals, but when magma cools quickly, it does not have time to develop big crystals, and therefore form small crystals. If intrusive rocks cool underground, and the temperature is higher underground, will it take a shorter, or longer time to cool

Answer 9

the impression is fossil (in sec 2)

Answer 10

What VIdeo, Voltage?

Answer 11

i did the same thing last year buh i 4got the video

Answer 12

this should make things easier

Answer 13

Thanks, Thats Better.

Answer 14

Answer 21

METAMORPHIC ROCK

1. Formation of metamorphic rocks. Metamorphic rocks are created by the physical or chemical alteration by heat and pressure of an existing igneous or sedimentary material into a denser form.
2. Regional And Thermal
Limestone: Sedimentary
Sandstone: Sedimentary
Shale: Sedimentary
Granite: Igneous
