Warm Up Day 1: Session 40 Soil

1. How does the formation of soil relate to tectonic action? In other words, how is new rock being brought to the Earth’s surface?

2. List 4 ingredients of soil:

3. What causes soil to form?

4. T/F The composition of soil is the same no matter where you are on Earth.

5. What does this statement mean?: “When we learn about the origin of rocks, we also learn about the history of the Earth.”

Warm Up Day 2:Watch Discovery Ed Video Geologists’ Notebook: What Exactly are Minerals? Sections 2 & 5 http://app.discoveryeducation.com/search?Ntt=geologists+notebook+what+exactly+are+minerals

Copy the following statements in your notebook and after watching the video, fill in the blanks:

Minerals form as _____________ cools inside the crust, or as _________hardens on the surface.

When these liquids ________ to a solid state, they form crystals. When elements and compounds that are _____________ in water leave

a solution, ________________ of minerals occurs.

Rock Sorting

1. Create a Chart in your Notebook like the one below2. You and your partner sort your rocks into the appropriate category.3. Fill in the chart by the characteristics of each type of rock and how they

were formed. Use p. 79A in your Textbook.4. At the bottom of your chart: Think and answer: How does the structure of

the rocks reflect how they were formed?

Warm Up Day 4: Human Impact Session 43

View the video loop of the satellite pictures of the state of Rondonia in Brazil from 2000-2010. Answer the following questions: http://earthobservatory.nasa.gov/Features/WorldOfChange/deforestation.php

1. Given the stems pedo=foot, and sphere=circular layer, where would you infer the Earth’s pedosphere is located?

2. What are the ways we humans use the soil?3. In what ways can a human population impact the pedosphere?

4. How was technology used to monitor the soil for impact?5. How can technology be used to help prevent erosion?

This pattern follows one of the most common deforestation trajectories in the Amazon:

Legal and illegal roads penetrate a remote part of the forest, and small farmers migrate to the area. They claim land along the road and clear some of it for crops. Within a few years, heavy rains and erosion deplete the soil, and crop yields fall. Farmers then convert the degraded land to cattle pasture, and clear more forest for crops. Eventually the small land holders, having cleared much of their land, sell it or abandon it to large cattle holders, who consolidate the plots into large areas of pasture.

All major tropical forests—including those in the Americas, Africa, Southeast Asia, and Indonesia—are disappearing, mostly to make way for human food production, including livestock and crops.

Although tropical deforestation meets some human needs, it also has profound, sometimes devastating, consequences, including social conflict and human rights abuses, extinction of plants and animals, and climate change—challenges that affect the whole world.
