To identify the key characteristics of the three major rock types
Types of Rocks – name the three major rock types and how they are formed:
1.
Sedimentary – formed from sand, shells, pebbles, and other particles
2. Metamorphic – formed by heat and pressure
3. Igneous – formed when magma cools and hardens
List six key characteristics that can help with rock identification:
1.
Crystals
4. Glassy surface
2.
Fossils
5.
Ribbonlike layers
3.
Gas bubbles
6.
Sand or pebbles
Name and describe the six rocks that you find:
1.
Conglomerate – made of pebbles, stones, smaller particles pressed together by waves or
water; usually found in large expanses or beds
2. Limestone – fossils; formed when seashells and marine animal skeletons were
compressed along with other sediment; often found near oceans or lakes
3. Basalt – gas bubbles from hot lava as it cools; usually dark in color; most common rock
in Earth’s crust and makes up most of ocean floor
4. Gneiss – ribbon-like layers; formed from other rocks that have been squeezed and
heated; often seen on mountainsides
5. Obsidian – glassy surface; lava cools quickly so no crystals can form; found near
volcanic lava flows; used to make arrowheads (very sharp edges)
6. Marble – has crystals; formed when limestone is subjected to heat & pressure; often used
in construction or sculpture
How Rocks Change - name and describe the ways in which rocks change:
1.
Heat and pressure – temperature increase below Earth’s surface and can melt rocks; then
rocks are pressed upon from layers above
2. Melting – need 600-1300°C to melt rock
3. Cooling – any rock cooled from magma is igneous; lava cools outside – extrusive;
magma cools inside - intrusive
4. Weathering and erosion – wind, water, temp changes break rocks apart into sediment,
which is transported by wind and water
5. Compacting and cementing – sediment builds up in layers and weighs down on layers
below; weight presses sediment together and compacts them; water helps cement them
together
