What is Mohs scale
100
A process of a rock hardening
What is Cementation
100
Longitudinal section of rock layers in a certain area

mineral
a mineral is an inorganic solid, formed in nature, has a definite chemical makeup, and a crystalline structure
200
Sedimentary rock consisting of fragments of various sizes formed by cementation
What is . Conglomerate
200
correlation- A relationship or a connection between 2 or more things(rock layers)
What is correlation
200
divergent: a type of plate movement where plates move apart
What is divergent
300

Logical reasoning based on prior knowledge
300
a mixture of two or more metals – example: brass, bronze
What is Alloy and give two example of them
300
Pertaining to structural change due to heat and pressure

mass movement- Bulk movements of soil and rock debris down slopes.
What is mass movement
300
Variable: a factor that can change the result of the experiment
What is variable
400
Organic- Derived from natural or living organisms. Inorganic- Not derived from living or dead organisms
What is the difference between organic and inorganic
400
layers as a result of flattening of mineral grains
What is Foliated
400
Recrystallisation- when pressure and heat breaks and rearranges the bonds that hold atoms
Compaction- sediments packed firmly as a result of the weight of overlying deposits.
What is the difference between recrystallization and compaction ?
400
Erosion-The process by which the weathered rocks are picked up and moved by wind, water, and glaciers.
What is erosion
400
subduction: the process by which, when two plates converge, a more dense tectonic plate sinks and melts
What is subduction
500
qualitative: observations including sights, sounds, smells, and textures
quantitative: expressed in numbers
What is the difference between qualitative and quantitative?
500
streak: the residue left behind by a mineral when rubbed against a surface
Ore- a rock rich in minerals that could be mined for profit
What is the difference between streak and ore?
500
A series of processes by which a rock changes from one rock type to another, over time.
What is rock cycle
500
Break down of rocks and soil through contact with atmospheric conditions.
What is weathering
500
convection: circular motion in a fluid in which the warmer, less dense portions rise and cooler, more dense portions sink
