Which feature would “young” mountains have—sharp peaks or rounded tops? Sharp Peaks
MYP Unit Question: How does land change? Area of Interaction: Environment Learner Profile: Caring and Principled Standard: Investigate the scientific view of how the Earth’s surface is formed.
Bell Ringer: Study Jams Video Learning Target: Today I’m learning how gravity and water cause erosion because I want to know if I can prevent it. Work Session: Notes – Erosion by Gravity Closing:

Erosion by Gravity p
GGravity is the force that moves rock and other materials downhill. If it’s written in BLUE, write it down under the flap. Erosion Gravity is the... Erosion by Gravity Erosion by gravity.
Gravity causes processes that move sediment downhill.
Types of Mass Movement LLandslides MMudslides SSlump CCreep
Mass movement can be fast or S L O W.
LaConchita Landslide Example
Sycamore Canyon Landslide Example
Las Colinas (view from the top) Example
Las Colinas (large view) Example
Mount St. Helens Mudflow (Lahar) Example
Slump – occurs suddenly
Creep - occurs slowly
Erosion by Water Moving water is the major agent of erosion that has shaped the Earth’s land surface p
