What is weathering?

• the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
• chemical or mechanical process that breaks down and changes rocks on or near Earth's surface and whose rate is influenced by factors such as precipitation and temperature.
• removal and transport of weathered material from one location to another location by agents such as water, wind, glaciers, and gravity.

What is erosion?

• removal and transport of weathered material from one location to another location by agents such as water, wind, glaciers, and gravity.
• the long-term average of variation in weather for a particular area.
• chemical or mechanical process that breaks down and changes rocks on or near Earth's surface and whose rate is influenced by factors such as precipitation and temperature.

How are islands formed in the ocean?

• Wind movement
• Metamorphic rocks
• Volcanic eruptions

How many crustal plates is California located on?

• one
• three
• two

What is the correct order?

• magma to lava
• lava to lava
• lava to magma

Once the volcano erupts on Earth, what is most likely to occur?

• lava cools and turns into a sedimentary rock
• lava cools and turns into an igneous rock
• lava cools and turns into a metamorphic

How can plants prevent erosion?

• Plant roots grow in rocks, breaking the rocks
• Plants slow down the runoff
• Plants receive energy from the sun to create photosynthesis.

What is the lithosphere?

• A layer of solid brittle rock that comprises the outer 100 km of Earth.
• The layer where storms occur
• The layer where the  magnetic field interacts with solar wind.

What is frost wedging? How does it impact the Earths surface?

•  is the coating or deposit of ice that may form in humid air in cold conditions, usually overnight. It increases the ability for lava to enter Earth.
• It occurs when water repeatedly freezes and thaws in the cracks of rocks. It causes an increased rate of exposure to weathering and erosion.

What is a sand dune?

• a dune is a hill of loose sand
• is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak.
•  largely level expanse of land at a high elevation.
