Which Is It: Weathering or Erosion?
Weathering The gradual breaking down of rock to smaller pieces (sediments).
Erosion A process that transports rock, soil or sediment to different locations.
1. The Colorado River has worn down the land in Arizona to form Grand Canyon. Is this weathering or erosion?
2.You have a sandstone wall in your front yard. After a heavy rain, you see loose pieces of the sandstone. Is this weathering or erosion?
3. You notice that a limestone statue at your church has become pitted. You are notified by the city that there has been acid rain in your neighborhood. Is this weathering or erosion?
4. The cold weather has caused your cement walkway to break up. Is this weathering or erosion?
5. The Sahara Desert has many miles of sand dunes. Is this weathering or erosion?
Landform Activity for review. DESTRUCTIVE WEATHERING #1 A rock heats in the sun and cracks.
Changes to the Earth’s Surface Grade 5 Science. Landforms Landforms are the physical features on the Earth’s surface such as, valleys, rivers, mountains,
REVIEW OF WEATHERING AND EROSION. WHAT WORD(S) SIMPLY DESCRIBE WEATHERING Breaking down Remember this is different from erosion There are two types of.
True or False: The Earths surface has stayed the same for thousands of years.
Sedimentary Rocks. 1) Formation of Sedimentary Rocks- Sediments- loose materials such as rock fragments, mineral grains, and bits of shell that have been.

Weathering, Erosion, and Deposition By: William Stephens.
Chapter 8, Section 3. Wind Erosion Occurs when air picks up loose material and transports it elsewhere. Usually cant pick up heavy sediments. Carries.
Chapter 9, Section 3. The Shore Ocean Shoreline Where land meets the ocean. Surface waves, tides, and currents cause shorelines to constantly change.
Lesson 3 – page 3. To learn what is erosion: Abrasion Hydraulic action Attrition Solution To learn what is transportation: Traction Saltation.

Weathering This week we write it down if its in ORANGE. Photo: Grand Canyon, National Park Service.
Sedimentary Rocks Rocks made of bits & pieces of other rocks.
1890 Erosion The first five pictures of this presentation are of the same rock, just in different time periods. Pay attention to the dates on the side.
Weathering and Soil Formation Chapter 10. Old and New Mountains The Appalachian Mountains appear very different from the Sierra Mountains. The Appalachians.
Weathering and Erosion. Weathering The breakdown do the materials of Earths crust into smaller pieces.
Soil The product of weathering of rocks Soil is made from rocks, minerals (mainly sand and clay), and organic material. Soil forms layers of different.
What? Where? Why? How? Who?. What are we learning today? Waterfalls: How do differences in rock hardness affect them? What are the main features / parts.
1 COASTS. 2 What processes make coasts change shape? Erosion attrition abrasion corrosion hydraulic action Deposition traction saltation suspension solution.
Erosion. Definition Erosion is the picking up and carrying away of pieces of weathered rock.
Igneous Rocks Igneous means Fire in Latin Many are produced by Volcanos Some are produced when underground magma cools and hardens.

Agents of Erosion. Erosion The process by which water, ice, wind or gravity moves fragments of rock and soil.

Weathering is the break- up of rock due to exposure to the atmosphere.

Rates of Weathering What is differential weathering? How does surface area affect the rate of weathering? How does climate affect the rate of weathering?
