Rocks! A Rock is a _________________________ formed ____________________ that is usually made up of one or more _______________________________. Rocks vs. Minerals Rocks Minerals Examples: Rocks with NO minerals… _____________________________ is a glass like rock and does not have a crystal structure. _____________________________ is made of dead plants. Rocks with 1 or more minerals… _____________________________ can be made entirely of calcite. _____________________________ is made of several types of minerals Our world is built of rocks! Rock is so common and has many purposes… 1.__________________________________________________________________________________________________________ _______________________________________________________________________________ 2.__________________________________________________________________________________________________________ _______________________________________________________________________________ Rocks change as they move through the rock cycle. The rock cycle is a set of ________________________ ____________________________ that ______________, ___________________________, and ______________________________ and _______________________________ rock! - Rocks are classified by how they _________________________. - There is no particular order to the rock cycle. - There is no ________________________ and no _______________________. - These changes take __________________________ to ______________________ of years. Types of rocks Igneous - __________________________________________________________________________________ _____________________________________________________________________________________________ Sedimentary - ______________________________________________________________________________ ____________________________________________________________________________________________________________ ______________________________________________________________________________ Metamorphic - ____________________________________________________________________________ ____________________________________________________________________________________________________________ ______________________________________________________________________________ 3.2 Igneous Rocks Magma – Molten rock that is ______________________ the surface of the Earth. When magma reaches the surface of the Earth it is called ___________________. Properties of Igneous rocks 1. Composition – refers to the level of __________________________ High Levels of Silicate Minerals Low Levels of Silicate Minerals Color = Color = 2. Origin Intrusive – Extrusive – 3. Texture Large Crystals form from ____________________, which cools _________________________. Small Crystals form from ____________________, which cools _________________________. 3.3 Sedimentary Rocks Some rocks form from rock particles. Most sedimentary rocks form from loose __________________________ that gets _________________________ ___________________________. Sedimentary rocks can be made of other rock particles and are classified by particle size. Ex. Big particles (pebbles and bigger) _________________________________________________ Smaller particles – _________________________________________________________________ Sedimentary rocks can also be made of plants or shells Ex. Plants (formed in swamps) - ______________________________________________________ Shells (dissolved by ______________ or not) - _______________________________________ 3.4 Metamorphic Rocks Heat and Pressure can _____________________________ a rock Because pressure and temperature increase with depth, rocks change ____________when they are buried __________________ in the crust. The deeper the rock, the more heat and pressure it is exposed to, the more it changes. Foliated vs. Nonfoliated Rocks Foliation is _________________________________________________________________________________ _____________________________________________________________________________________________. Foliation occurs when rocks are under pressure. Rock must contain _________________________________________ type of mineral. Nonfoliated rocks occur when heat and pressure are applied to rocks that contain _____________________________ kind of mineral Ex. Limestone becomes _________________________
