Sedimentary, igneous, metamorphic…They are classified according to how they are formed. $100 What are rocks?

Bits of rock, sand, shells, or the remains of plants or animals. $100 What are sediments

They are made of chemicals, some are rare gems, their names end with “ite” $100 What are minerals?

The process directly responsible for the breaking down and the wearing away of rock. $100 What is weathering?

Gravity, wind, moving water, and glaciers can transport or move sediments form one place to another. This process can change Earth’s landscape. $100 What is erosion?

Earth’s crust is not one solid piece of rock, it is broken into huge pieces which are called. $100 What are plates?

Fossils are generally found in this type of rock. $100 What is sedimentary?

To test the resistance of a a rock’s surface to scratching $100 What is the Moh’s Scale of Hardness?

It is a hard, solid part of the earth’s surface, most are made of combinations of minerals $100 What are rocks?

Geologists believe the Earth was formed this long ago. $100 What is 5 billion years ago?

I study rocks $100 What is a Geologist?

This is the easiest property to observe on a rock or mineral $100 What is color?

This term describes how a rock or mineral sample reflects light. $100 What is luster?

$100 What is acid? This liquid is used to test a rock or mineral for a base.

$100 What is bubbles when acid is placed on it.? A chemical property is evident if the mineral...

The hard, solid crust of the Earth. The layer where we mine rocks and minerals. $200 What is lithosphere?

The way some minerals naturally break into smaller pieces, rocks never do this! $200 What is Cleave?

Geologists only look at this in formations of sedimentary rocks. $200 What are layers?

The size of the pieces that make up the rock. $200 What is texture?

The scientific names of minerals sometimes, but not always, end with this $200 What is “ite”?

All rocks are composed of these. $200 What are minerals

Another name for lithosphere. This is the rocky surface of the Earth where we live. $200 What is crust

$200 What is a 1-2? Rocks are given this rating when they can be scratched with a fingernail.

I have a hardness of ten $300 What is a diamond?

The Earth’s huge crustal pieces are drifting and moving on this layer. $300 What is mantle?

The electricity test is performed to discover if this substance is present in a rock $300 What is metal?

This type of rock is made from hot, melted rock material as it cools and solidifies $300 What is igneous rock?

A geologist named Alfred Wegener hypothesized that 200 million years ago the continents were joined together into this super continent. $300 What is Pangea?

This rock has been changed by heat and pressure over a period of time $300 What is metamorphic?

What information would probably be the most helpful in identifying a mineral sample? $300 What is hardness and streak?

This part of the earth is made of solid nickel and iron $300 What is the inner core?

This surrounds the outer core and is made up mostly of hot, liquid rock called magma. $300 What is the mantle?

$100 The natural breakage of a mineral on 1, 2 or 3 planes What is cleavage? $300

Only these have a consistent hardness because they are chemically the same $400 What are minerals?

This mineral has cleavage in three directions, forming a cube $400 What is salt?

We are the basic building blocks of all rocks, we are made up of 1 or more chemicals $400 What are minerals?

The splitting of a mineral, the surface is usually very shiny when it does this $400 What is cleave?

One or more chemicals, the basic building blocks of rocks, rare gems, “ite” $400 What are minerals?
