Chapter 7

Section 2 NotesSlide2

Fact Finders

Use your textbook, pages 188 - 194, to fill in the blanks.

_______ is a mixture of weathered rock, decayed organic matter, mineral fragments, water & air.

Soil formation is influenced by ___________, ___________, types of ________, types of __________ & length of ______ that rock has been weathering.

Clay, silt & sand are small particles of _________.

Decaying, dark-colored plant & animal material is called ________.

Small spaces between soil particles may be filled with _______ or _______.Slide3

Answers_Soil_ is a mixture of weathered rock, decayed organic matter, mineral fragments, water & air.

Soil formation is influenced by _climate_, _slope of land_, types of _rock_, types of _vegetation_ & length of _time_ that rock has been weathering.

Clay, silt & sand are small particles of _sediments_.

Decaying, dark-colored plant & animal material is called _humus_.

Small spaces between soil particles may be filled with _air_ or _water_.Slide4

6. Different layers of the soil are called _h____________.

7. The top layer is called Horizon ___ and may be covered with organic ________ that may turn into humus.

8. Horizon A is a fertile layer of soil with more _______ and less ________ and mineral particles than other soil horizons.

9. Horizon B, or the 2

nd

layer of soil, contains less ______ & is lighter in color than the A horizon.

10. Minerals travel from A horizon to B horizon in a process called __________.Slide5

Answers6

.

Different layers of the soil are called _horizons_.

7. The top layer is called Horizon

A

and may be covered with organic

matter

that may turn into humus.

8. Horizon A is a fertile layer of soil with more _humus_ and less _rock_ and mineral particles than other soil horizons.

9. Horizon B, or the 2

nd

layer of soil, contains less

organic matter

& is lighter in color than the A horizon.

10. Minerals travel from A horizon to B horizon in a process called _leaching_.Slide6

11. Horizon C is the _______ layer of soil. It has very little ________ matter and is not strongly affected by leaching.12. The C Horizon contains rock, the _______ material of the soil.

13. Glaciers can deposit soil that did not form from the ________ beneath it.

14. Different regions have different __________ that affect soil development.Slide7

Answers11. Horizon C is the

third

layer of soil. It has very little

organic

matter and is not strongly affected by leaching.

12. The C Horizon contains rock, the

parent

material of the soil.

13. Glaciers can deposit soil that did not form from the

ground/rock

beneath it.

14. Different regions have different

climates

that affect soil development.Slide8

15. ______ rock affects soil formation & type of ______ that grows in a region.16. _________ affects soil development because the longer the weathering has occurred, the less the soil resembles the parent rock.

17. Soil on steep ______ develops poorly.Slide9

Answers15. Parent rock affects soil formation & type of vegetation

that grows in a region.

16.

Time

affects soil development because the longer the weathering has occurred, the less the soil resembles the parent rock.

17. Soil on steep _

slopes

_ develops poorly.
