What is a rock
A naturally occurring solid mixture of one or more minerals or organic matters.
|
What are the characteristics of the crust.
Composed of igneous, metamorphic and sedimentary rock.
|
What is convergent boundary ? What dose it form ?
Two tectonic plates that collide together and it forms mountains ,trenches with sub zones , and volcanoes .
|
What is a rock cycle.
The continual process by which new rock form from old rock.
|
What are the five physical layers of the earth
Lithosphere Asthenosphere, Mesosphere,
Outer core, inner core |
What is divergent boundary?what does it form?
When two tectonic plates go the opposite direction of each other it forms volcanoes on the mid ocean ridge.
|
What are the key features of a sedimentary rock
The layers, clastic, and organic
|
What is a tectonic plate
Peices of the lithosphere that move around on top of the Asthenosphere
|
What is a transform boundary ? What does it form ?
When two tectonic plates slid verticle of each other on Is going up and one is going down it creates a fault a an earthquake.
|
What isobar are the key features of a metamorphic rock.
Non-Folicated
Folicated |
Explain the process of Sea- Floor spreading at the mid- ocean ridge.
Sea floor spreading is the process by which new oceanic lithosphere forms as magma rises towards the Earths surfaces and solidifies.
|
How are convection currents able to go to the top nd the bottom of the mantle?
Sea floor spreading- Magma rises to the Earths surface and solidifies making rocks and when fault line whit earthquake soccer the rocks fall through the fault. Less dense float and more dense sink .
|
Explain how to create a sedimentary rock.
Grains of sand from weathering and erosion, yet compaction and cement action and becomes a sedimentary rock.
|
Where is the ocean floor new, and where is the ocean floor the oldest.
The ocean floor is new by the mid ocean ridge
The ocean floor is oldest farther away from the mid ocean ridge at a trench |
What is deformation
The action or process of rocks changing shape due to stress .
