Weather and Climate
What is weather?
Short-term atmospheric conditions
What are the three main rock types
Igneous, Sedimentary, Metamorphic
What are tectonic plates?
Large pieces of Earth's Crust
Name Earth's outermost layer
Crust
What is weathering?
Breaking down rock
What is Climate
Long term weather patterns
How does magma become igneous rock?
What happens at convergent boundaries
They collide or converge
Which layer is the hottest
Inner Core
What is erosion
Movement of sediment
Why does the weather change faster than the climate?
Climate is measured over long periods
What changes sediment into sedimentary rock?
Compaction and cementation
What happens at the transform boundary?
They slide past one another
What is mineral
Naturally occurring solid with specific properties
Difference between mechanical and chemical weathering?
Mechanical breaks physically; chemical changes composition
What tool measures temperature
Therometer
What causes metamorphic rocks to form
Heat and pressure
What natural events can plate movements cause?
Earthquakes and Volcanos
Name one property to identify minerals
Hardness, streak, luster, etc.
How can water cause erosion?
Moving water carries sediment away
What causes wind?
Uneven heating of Earth
Why is the rock cycle called a cycle?
Rocks continuously change form
Which layer do tectonic plates move on?
Mantle (asthenosphere)
What is hardness?
Resistance to scratching
Give one real-life example of weathering
Cracked sidewalks, rusting rocks, etc.
