Minerals
The building blocks of rocks
What are minerals?
Formed from cooled lava
What are extrusive igneous rocks?
The theory the arth's crust is broken up into plates and move
What is the theory of Plate Tectonics?
The ability to do work
What is energy?
An oceanic plate will subduct under a continental plate because .........
It is more dense
The property of a mineral to be shiny or matt
What is lustre?
Rocks formed from heat and pressure
What are metamorphic rocks?
Fold mountains are formed from (type of boundary)
What is convergent (continental - continental) boundary?
This type of enery is also known as stored energy
What is potential energy?
Fossils are found in this type of rock
What are sedimentary rocks?
The property of a mineral to break in a set way e.g. in sheets
What is cleavage?
Coal (formed from the remains of dead plants) is an example of this type of rock
What is a sedimentary rock?
Transform boundaries cause
What are Earthquakes (and tsunamis)?
electrical --> heat + light
The above diagram represents a ___________
What is an energy transformation?
A truck is lifted 1m above the ground and a mini is also lifted 1m above the ground, which has the most gravitational potential energy and why?
The truck as it weighs more
Small crystals in igneous rocks are formed when
the molten rock cools quickly
Granite is an example of what type of rock
What is instrusive igneous rock?
Divergent boundries cause what geological formation
What are mid ocean ridges?
The unit of measurement for energy
What is the joule?
Draw the layers of the Earth
List the proprties of minerals
-cleavage/fracture - transparency
- lustre - acid test
- colour - specific gravity
- streak
- hardness
Draw the rock cycle
(must show all rock groups and how they are changed into each other)
Draw the convection currents under two plates (one is oceanic and the other is continental) to show plates converging
Picture must show the the currents under one plate going clockwise and anitclockwise under the other
Write an energy chain to show what occurs in a coal powered power station
Explain the difference between independent, dependent and controlled variables, use an example in your response
Independent - the variable being changed
Dependent - what is being measured
Controlled - vriables that need to stay the same
e.g. to investgate how temperaure affets the size of crystals forme
Independent - temperature
dependent - size of crystal
controlled - same amount and type of substance, same containers
