Chapter 6: Changes to Earth's Surface
NGSS (Science Standard Addressed)
- ESS2.B: Plate tectonics and large-scale system interactions
Big Ideas
- The four major layers of the Earth are the crust, mantle, outer core, and inner core
- Earth's surface changes and is shaped by several things: wind, water, gravity, glaciers, and impacts
- Know the difference and sequence of weathering, erosion, and deposition. Weathering is the breaking down of materials, erosion is the carrying of weathered materials, and deposition is the dropping or settling of eroded materials
- The Earth is made up of several tectonic plates that are moving all the time
- There are boundaries between tectonic plates that have different names, and they move in different ways. At a convergent boundary, the plates push against each other. At a divergent boundary, the plates move apart. At a transform-fault boundary they slide past each other.
- 220 million years ago, the Earth was once a giant landmass with all of the continents combined. That land mass is known as Pangea.
- When pressure builds up along fault lines, the earth snaps and releases energy as waves. This is known as an earthquake.
- The Richter Scale measures the strength of an earthquake
- Magma that rises to Earth's surface and erupts from a vent is a volcano
Required Readings and Lessons
- How Does Earth's Surface Change? pp. 230-236 After Reading Assessment I
- What Are Plates And How Do They Move? pp. 240-244 After Reading Assessment II
- What Causes Earthquakes And Volcanoes? pp. 248-254 After Reading Assessment III
Above and Beyond (Choose one to be completed by the end of the unit)
To receive an A in science class, you must complete one of the activities below. They must be done very well and presented to the class in some form. If you have any questions, please ask Mrs. Stibbe.
