rock weathering
which type of weathering is not a type of stress?
what is chemical weathering
Stress that pulls two rocks apart.
tensional stress
a type of rock that is formed by the cooling down of magma
igneous
what are the three types of rocks in the rock cycle
igneous, metamorphic, sedimentary
what are the reasons engineers need to know about rocks?
to build safe buildings and bridges
what type of weathering is a tree root breaking something?
biological weathering
What are the three types of stress?
tensional, compressional, and shear
a type of rock that is formed by heat and pressure
metamorphic
what are the three ways rocks become the type of rocks they are?
heat and pressure, cooled magma, and cemented sediments
what can an engineer add to a building to keep it safe from dangers?
they can add a cement foundation and steel supports
what is physical weathering?
physical actions like wind, or water freezing and cracking a rock.
a type of stress that pushes two rocks together.
compressional stress
a type of rock that is formed by sediments being pushed and cemented together
sedimentary
how does a rock turn into a metamorphic rock?
it gets heat and pressure put on it
what does a geological engineer focus on?
learning about the earth
List the three different types of weathering
physical, biological, and chemical
a type of stress that pushes and pulls a rock in opposite directions.
shear stress
how does a sedimantary rock become an igenus rock?
the sedimentary rock melts into magma then cools down
what is compaction?
layers of sediment that have been cemented over time
a civil and structural engineer is responsible for what?
making sure a bridge is designed correctly
What is weathering?
Weathering is something that breaks up or destroys rocks.
What is stress?
the pulling or pushing pressure that breaks rocks
how does a metamorphic rock become a sedimentary rock?
it gets weathered down into sediments then cemented together
what is magma?
heated rock
if an engineer doesnt build something correclty what is something bad that can happen to it?
it can collapse, it could injure/kill people
