 The world’s population is increasing at an alarming rate.  All of these people need to eat.  However, less than 25% of the Earth’s land can be used.

Soil Conservation. How do we use the land to change the land? Mining – rocks and minerals are removed from the ground for profit by one of two methods:

1. _____nonrenewable resources that form in Earth’s crust over millions of years from the buried remains of once living organisms. Ex coal (fossil fuels)

Soil Conservation. Soil conservation means protecting soils from erosion and nutrient loss. Soil conservation can help to keep soils fertile and healthy.

EROSION CONTROL BY LAND MANAGMENT WHAT IS EROSION The detachment and transportation of soil particles from one place to other by running water, wind.

  We lose 1% of our topsoil every year because of erosion.  Ever heard of the Dust Bowl?  Read the book “Out of the Dust” by Karen Hesse?

Soil Erosion. What is soil erosion? A natural process of soil moving from one place to another.

SOIL DEGRADATION  When plants (trees & shrubs) are cleared from a site, soil is exposed to sunlight and the eroding effects of wind and water. Soil aeration.

SOIL Soil is a valuable natural resource.. Why? Because everything that lives on land depends on soil. People & animals eat food that grows in soil. Plants.

Human Impact. How do humans affect the Earth? Human activity can have a positive or a negative impact on the surface of our Earth. We deplete resources.

1 What is the cutting down all trees in an area? 2. What is cutting a pit in the surface? 3. What is the stripping the surface of the land? 4. What is the moving of sediments? 5. What do plant roots prevent?

1, What is soil conservation? 2, What methods prevent soil erosion? 3. What is a cover crop? 4. What is crop rotation? 5. What is contour plowing? 6. What is terracing? 7. What is windbreak?

1. What boundary do plates move apart? 2. What boundary do plates come together? 3. What boundary do plates slide past one another? 4. What boundary does a fault form at? 5. What boundary does a trench or a volcanic arch for at?

1. What is soil conservation?

 2. Methods to prevent soil erosion- cover crop, crop rotation, contour plowing, terracing, and windbreak.

3. Cover Crop-a crop that is planted in between harvests to reduce erosion and replace nutrients ex soybean and clover

 4. Crop Rotation-change crops from year to year so that nutrients do not get depleted

 5. Contour plowing-rows in a field are plowed in curves instead of straight lines.

 6. Terracing-one steep field is changed into a series of smaller fields.

 7. Windbreak-planting trees around a field to prevent wind erosion.
