If a rock is like a cookie then what material are the ingredients?
What are Minerals?
What is the Earth's crust made up of?
rock
What is a mineral?
Minerals are a pure and made of the same substance throughout.
Unlike erosion, which moves material, this process is the "in-place" breaking down of rocks.
What is Weathering?
This process, occurring at mid-ocean ridges, is evidenced by magnetic patterns on the ocean floor.
What is sea floor spreading?
What are the three types of rocks.
Igneous, sedimentary, metamorphic
There are three different type of rocks in the rock cycle.
What is igneous, sedimentary and metamorphic
This property describes how a mineral reflects light, using terms like "metallic" or "pearly."
Lustre.
This type of mechanical weathering occurs when water freezes in cracks and expands, prying the rock apart.
What is Frost wedging?
Compared to the continental crust, this type of crust is more dense and more mafic (basaltic).
What is oceanic crust?
Two processes that start with C are responsible for the formation of sedimentary rocks.
What is compaction and cementation?
You’ll likely find fossils in this rock type, formed from the accumulation of debris over time.
What is Sedimentary?
This term describes a mineral's tendency to break along flat, parallel surfaces.
What is Cleavage.
This is the primary agent of erosion in this photo of the Grand Canyon.
What is Moving water.
This nuclear process occurs at a constant, spontaneous rate and is used as a "geologic clock."
What is radioactive decay?
The process that changes rocks from one type to another that has no begining or end.
What is the Rock Cycle.
Intense heat and pressure transform existing rocks into this type, like limestone turning into marble.
What is Metamorphic?
A measure of a minerals resistance to scratching is called.
Hardness.
The type of weathering that occurs when iron reacts with oxygen and water, giving rocks a reddish hue.
What is chemical weathering.
This process transfers heat energy through molecular collisions without the bulk movement of material.
What is conduction?
What is the difference between a rock and a mineral?
Rocks are made up of 2 or more minerals. Minerals are made up of the same substance throughout.
This rock type forms from the cooling and solidification of molten magma or lava.
What is Igneous?
List at least 4 properties of minerals.
Color, streak, lustre, magnetism, transparency and hardness.
Give one example of chemical weathering and one example of physical weathering.
Answers will vary!
It is the specific process where less dense, warm water rises while more dense, cool water sinks.
What is convection?
