Fun Facts
The name of a famous ancient circular rock monument in England
What is Stonehenge
Formation of Igneous rocks
Igneous Rock --> Metamorphic Rock
What is the application of heat and pressure
Physical actions, such as wind, or water freezing and cracking a rock
What is physical weathering
Reasons engineers need to know about rocks
to build safe and strong bridges, roads and tunnels
Rocks that come from space are called...
Meteorites
Rock made from layers of sediment compacted and cemented together
What is Sedimentary Rock
It becomes magma and then becomes igneous rock
List the three main types of weathering
Physical, chemical and biological
What kind of engineer is responsible for making sure a bridge is correctly designed and built?
The word "igneous" comes from which Latin word
Ignis-- meaning fire
Existing rock changed by heat and/ or pressure
What is metamorphic rock
Layers of sediment become pressed together over time
What is compaction
How does biological weathering occur?
when living organisms break rocks
What kind of engineer focuses on learning about the Earth
A geological engineer
The crystal comes from which Greek words?
Kyros-- meaning icy cold
This rock type includes granite and basalt
Process where the rocks that form Earth's crust are continually destroyed and remade
Rock Cycle
Decomposes or decays rocks and minerals
If an engineer did not learn about the rocks supporting his bridge foundation, and design and build the bridge appropriately, the bridge could break or collapse.
how an engineer’s mistake involving rocks could harm people
How much of the mined gold gets returned to Earth
More than half. Most of it is buried in subterranean bank vaults
This rock type can contain fossils or fragments of other rocks
Sedimentary Rocks
Rocks are formed by (give 2 examples)
Melting, cooling and solidifying, changing through heat and pressure, weathering and erosion, compression and cementation
How is weathering different than erosion
Erosion includes the transportation of the rocks and soil away from the site of degradation.
What are things an engineer must take into consideration before building a dam
Rock sizes, location, and type; weathering and erosion; how much water will flow to and through the dam; size of the dam; cost; safety issues; electricity generated; effects on the fish and wildlife around the dam, and upstream and downstream; how much land will be flooded; how many people and/or businesses will have to move and/or be affected; how long it will take to build; what it will cost to maintain it…
