Science Day 3 Flashcards
Study for the whopper (41 cards)
Inner Core
Dense ball of solid metal
Outer Core
Layer of molten metal that surrounds the inner core
Mantle
Layer of solid, hot rock, 40 km beneath the surface
Lithosphere
Uppermost part of the mantle
Asthenosphere
Softer part of the mantle below the lithosphere and is hotter and under increased pressure
Lower Mantle
Solid material extending all the way to the Earth’s core
Crust
Layer of solid rock on the Earth that we live and walk on
Radiation
The transfer of energy with no direct contact
Conduction
The transfer of energy by direct contact
Convection
The transfer of energy
Continental Drift
A slow movement of Earth’s continents moving away from each other
Seafloor Spreading
Seafloor is spread apart along both sides of a mid-ocean ridge
Plate Tectonics
Explains the movement, formation, and subduction of Earth’s plates
Transform boundaries
Place where 2 plates slip past each other while moving in opposite directions
Divergent Boundaries
Where 2 plates pull apart
Convergent Boundaries
Place where 2 plates come together
Stress
Force that acts upon a rock to change its shape or volume
Tension
Pulls on the crust, and stretching it so it becomes thinner in the middle
Compression
Squeezes on a rock until it folds or breaks
Shearing
Pushes a mass of rock in two opposite directions
Strain
A change in a rock
Faults
Breaks in the Earth’s lithosphere
Earthquakes
Vibrations in the ground
Normal Fault
Form when forces pull rocks apart along a divergent boundary
