Rock types
how is igneous rocks form
hardened lava
how is igneous rock transformed into a metamorphic rock
by heat and pressure
tensional stress
pulls two rocks together
physical weathering
physical action breaks the rock
why should engineers know about rocks
to make sure its safe for buildings or if natural disasters are going to happen
how is a metamorphic rock formed
rock changed by heat and pressure
what happens when metomorphic rock melts and then cools
it turns into magma and then turns into a igneous rock
compressional stress
pressed together
chemical weathering
when the rock is chemically broken down
what is a geological engineer
they learn the Earth
which rock is made from layers of sediment that are compacted together
sedimentary rock
compaction
pressing things together
physical stress
it can deform elastically or plastically and it can break or fracture
biological weathering
when living organisms break the rock
the physical properties of engineering rocks
color, hardness, density, etc
what are 3 rocks
sedimentary, igneous, metamorphic
what 3 rocks are in the rock cycle
igneous, metamorphic, sedimentary
shear stress
pulled on one side but pushed on the other side
weathering
process that breaks up rocks
engineers
How is magma formed.
Sedementary, Metamorphic-melt
metamorphic-megma
melt
confining
pushed down by the weight
when the rock is chemically broken down
chemical weathering
how many types of enginering rocks are there
