True/False

Indicate whether the sentence or statement is true or false.

1.

The most precise way to measure slope is with a transit level.

2.

Uplands, terraces, and flood plains make up the three general make up the three general classes of landscapes.

3.

Flooding is a severe land use limitation for lawns, gardens, and landscaping.

4.

Mucks and peats have a high content of water, contain more than 20% organic matter, and when artificially drained, they tend to compress, dry, shrink, and decompose.

5.

Silt is sticky and plastic when moist; it will form a flexible ribbon when presses between the fingers.

6.

Surface soil texture refers to the texture of the normal plow layeror the upper 7 inches of topsoil.

7.

A uniformly bright-colored soil is a sign of a soil that is well drained to excessively drained and does not have a seasonal high water table within 48 inches of th surface.

8.

In mottled soils, the longer the duration of saturation, the more extensive the gray color.

9.

Bedrock within 60 inches of the soil surface is not considered a limitation for basements and septic tank absorption fields.

10.

Fragipans and dense glacial till can limit the function of septic tank absorption fields.

11.

A good site for buildings with basements is in nearly-level or gently-sloping soils with sandy subsoil textures.

12.

A septic tank absorption field should be located within 50 feet of a stream or other body of water.

13.

Clayey surface soil textures are good for roads and streets because they are considered “heavy soils”.

14.

Shallow-rooted trees should be selected for landscapes with a hard dense soil layer within a depth of 40 inches.

15.

A perimeter (curtian) drain is required around some septic tank absorption fields to carry the excess effluent away.
