Geology 12 Unit 2 – Review Game!!! Using your whiteboard, write down your answer. Keep your answer to yourself until asked to show.

I am an intrusive rock with very large crystals. What rock group do I belong to?

Igneous Rock Instrusive – cools inside the earth, giving time for it to crystallize.

I am often a great place for fossils to form as my sediments wrap around the organism. What rock group do I belong to?

Sedimentary Rock Layers of sediments help to hold fossils in place.

I am basalt and volcanic in origin. I make up the ocean floor crust. What rock group do I belong to?

Igneous Basalt is volcanic rock and formed when lava cools on the ocean floor.

I go through a lot in my day! Extreme heat and pressure are applied to be all the time…its exhausting!!! What rock group do I belong to?

Metamorphic Morph = change Pre-existing rock can change into metamorphic rock when heat and pressure is applied to it.

I think I’m pretty unique with my very distinct layers of sediment. What rock group do I belong to?

Sedimentary Rock *contains the word sediment

My name is Obsidian. I am a glassy volcanic rock. What rock group do I belong to?

Volcanic rock = Igneous

I make floors gleam! I was created when heat and pressure were applied to my parents: “Limestone Ma” and “Limestone Pa” What rock am I?

Marble Limestone is a sedimentary rock Heat and pressure change it into a metamorphic rock: marble.

In order for me to even have a chance to form, weathering and erosion of pre-existing rock needs to happen first! What rock group do I belong to?

Sedimentary Weathering and erosion break down existing rock into sediments.

There are two of us that make up the earth’s crust. We float on top of the earth’s mantle and move with the help of convection currents. I’m am greater in density but am thinner then my ‘partner in crime’. What type of crust am I?

Oceanic Crust Oceanic – density 3g/cm 3 Continental Crust – density 2.7g/cm 3 Crust – 50km+ thick Ocean - ~ 7km thick

I belong to a large family. There are 119 of us to be exact. We differ greatly in atomic mass and atomic number. What are we?

Elements

I occur naturally on earth, have a crystal shape and even have my very own chemical formula! What am I?

Minerals

My name is Opal, I’m kinda like a mineral but don’t have all their characteristics, but I’m still fascinating to look at! I am not a mineral, I am a ________.

Mineraloid

Geologists prefer to conduct this test to find out the authentic color of a mineral.

Streak Test

I can’t stand a chance against a fingernail, a nail, a copper penny or even my close neighbour Gypsum. They all scratch me  They say I’m quite the softy. What mineral am I?

Talc

I am the strongest of all minerals and quite popular to say the least. Who wouldn’t like me? I look nice in jewellery and I am a pretty reliable drilling aid. What mineral am I?

Diamond

I am the basic unit of an element. I consist of protons, neutrons and electrons. What am I?

Atom

To form me, you need sediments…lots of sediments. If I wanted to become sedimentary rock there are three ways I can. Lists the three formation processes.

Lithificaton Compaction Cementation

I am a type of sedimentary rock that is mainly composed of plants, shells, or bones. What type am I?

Organic Sedimentary Rock Other sedimentary rock types: clastic, chemical

Hi there, I’m Oxygen (O 2 ). Can you tell me my atomic mass? Atomic number?

Atomic Number (# of P) Atomic Mass (P+ N)

I originate from the Earth’s mantle and cool on the Earth’s surface. I was once __________ but now am __________.

Magma, Lava

These two rock groups form from pre-existing rocks! What are they?

Sedimentary Metamorphic
