and natural resources?
GPSWhich Standards are students learning in this unit?
S6E5. Students will investigate the scientific view of how the earth’s
surface is formed.
i. Explain the effects of human activity on the erosion of the earth’s
j. Describe methods for conserving natural resources such as water,
soil, and air.
S6E6. Students will describe various sources of energy and with their
uses and conservation.
a. Explain the role of the sun as the major source of energy and its
relationship to wind and water energy.
Both of these remove plant roots that anchor soil.
How farming contributes to erosion:
Pulls nutrients out of the soil, leaving
the soil vulnerable to erosion.
Dust Bowl –
This removes plants and roots that anchor soil.
What is soil conservation?
What methods prevent soil erosion?
What is a cover crop?
What is crop rotation?
What is contour plowing?
What is terracing?
What is windbreak?
Methods to prevent soil erosion-cover crop, crop rotation, contour plowing, terracing, and windbreak.
Cover Crop-a crop that is planted in between harvests to reduce erosion and replace nutrients. Ex:soybeanand clover
Crop Rotation-change crops from year to year so that nutrients do not get depleted
Contour plowing-rows in a field are plowed
in curves instead of straight lines.
Terracing-one steep field is changed into a series of smaller fields.
Windbreak-planting trees around a field to
prevent wind erosion.
