Define Renewable energy?
Energy that comes from resources which is naturally replanishable.
100
Order of Earth's layers?(From inside to outside)
Inner Core,Outer Core, Mantle,Asthenosphere,Lithosphere,Crust
100
What is the texture of an igneous rock?
The texture of an igneous rock can be either fine grained or hard
100
What is relative dating?
Relative dating is when you can only give the order that rocks were formed.
100
What is the principle of horizontality
The principle of horizontality states that every rock layer was born flat
200
Positives and negatives of renewable energy
Positives are it will never run out and less maintenance. Negatives are hard to generate large amounts of energy and the supply can be hard to use like based on weather
200
What type of rock is the Ocean Crust made out of ?
Basalt
200
What are the 3 types of sedimentary rocks?
The types are Clastic,Organic and Chemical
200
What is the principle of superposition?
The principle of superposition states that the rock layer at the bottom is the oldest and the one at the top is the youngest.
200
What is the principle of cross cutting
The principle of a cross cutting states that an igneous intrusion is always younger than the rock it cuts across.
300
What is a prototype?
Prototype is the a preliminary model of something, especially a machine.
300
How do the plate tectonics move ?
Plate tectonics move when convection happens underneath earth's surface.
300
Where does magma forms?
Magma forms inside earth's core and in the mantle
300
What is absolute dating?
Absolute dating is the process of determining an age on a specified time scale.
300
What is Disconformity
Disconformity is when there is a gap and the layer above is sedimentary rock and the layer below is sedimentary rock.
400
As energy changes form what happens to most of it?
Most of it becomes thermal energy.
400
What is the name of the scientist that believed in continental drift?
Alfred Wegener
400
Tell me what is the crystal size for intrusive and extrusive rocks and where did they form
intrusive rocks crystal size are large and they form underneath earth's surface, extrusive rocks crystal size are fine grained and they form on earth's surface
400
What is an unconformity?
An unconformity is when there is a gap between rocks
400
What is a Nonconformity
Nonconformity is when there is a gap but the rock above is either igneous or metamorphic and the rock below is sedimentary rock.
500
Define,give examples,factors that affect it,formula and units of Kinect Energy
Kinect energy is energy created due to motion,jumping and running,factors that affect it are motion and velocity,Formula: 0.5 • m • v2,Jules.
500
What causes convection of the mantle?
Heat coming from inside earth's core.
500
Define and give examples of Clastic,Organic and Chemical sedimentary rocks.
Clastic sedimentary rocks are rocks made out of small pieces of other rocks,EX: Clay, Silt and Sand. Organic sedimentary rocks are rocks made out of significant amounts of organic carbon,EX:Coal, Lignite, Oil shale, or Black shale. Chemical sedimentary rocks are rocks made out of chemical precipitation,EX:Stalactites,Stalagmites and the rock Salt
500
What is an Angular Unconformity
An Angular Unconformity is when the layer of rock below is tilted while the one above is normal
500
What environments are fossils more likely to form in?
Fossils are more likely to form on lakes and on the bottom of deep oceans
