Seasons
What causes seasons?
The tilt of the earth's axis / direct or indirect sunlight
What is solidification?
it is when magma cools (hardens)
What does precipitation mean?
rain
What position is the Sun, moon, and earth during a lunar eclipse?
Sun, Earth, Moon
Which way is earth tilted in the winter?
away from the sun
What does compaction mean?
when sediments are deeply buried, placing them under pressure because of the weight of overlying layers
How can an area prepare for flash floods or flooding?
they can use precipitation data to determine when/where to post road closures and detours in areas that flood
What plate boundary causes mountain formations?
convergent plate boundaries
Name the seasons in order starting from winter
winter, spring, summer, fall
What is erosion?
When sediments are moved by wind, water, etc.
What is evaporation?
when liquid turns into gas
What is a divergent plate boundary?
Divergent boundary is when two tectonic plates split apart
Using the diagram, what season is shown at position C
Winter
What does deformation mean?
when something changes form due to natural geological processes.
What causes evaporation?
heat from the sun
How do metamorphic rocks form?
heat and pressure
What month does fall start?
What month does winter start?
Fall=September
Summer=Decemeber
What two sources are responsible for the flow of energy in the rock cycle?
the sun and earth's hot interior
Explain the process of evaporation
Evaporation is when the Sun heats up the surface of water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas.
True or false? Erosion aid in the break down and movement of rocks into sediments.
True
