Review Questions This test consists of 10 questions for reviewing Chapter 9. Read each statement and decide if it is true (T) or false (F). You have 10 minutes to complete the test.
Operator’s competence is essential for not to cause any ground damage.
T
F
The carrying capacity and surface structure are of minor importance for avoiding damages to ground and watercourses.
T
F
Sites with low carrying capacity should be harvested when there is frozen ground.
T
F
Terrain assessment is never carried out from the office.
T
F
When planning harvesting operations, one should have good knowledge of the district.
T
F
Aerial photos do not give important information about the terrain.
T
F
Harvesters are much more terrain-sensitive and require higher ground carrying capacity than forwarders.
T
F
Fully loaded forwarders behave in the same way as the half-loaded forwarders.
T
F
Generally, forwarders have shorter wheelbases than harvesters.
T
F
There are major variations in characteristics of moraines, till and sediments.
T
F
“Black earth” is a kind of productive peaty ground.
T
F
Assessment of the quality of the terrain must include what ground/soil types can be found at the harvesting site.
T
F
Mires and peatlands cannot be formed in areas with mild climates along the coast.
T
F
All productive peatlands have extremely high carrying capacity.
T
F
Silvicultural activities should be conducted on bedrock surface.
T
F
The bedrock is often exposed in various places at moraine/till sites.
T
F
Silt is poor in fine particles and does not have good ability to hold and transport water.
Clay soils are found in low parts of the terrain, often adjacent to lakes.
T
F
Sites with clay-dominated soils are not easy to distinguish because they are, or have been, cultivated.
T
F
If it is possible to roll the soil into a “thin thread” it consists largely of silt or clay.
T
F
Comprehensively reading the terrain provides foundations for planning operations.
T
F
On most tills the harvesting operation should not be adapted to vegetation.
T
F
The topography provides the harvesting teams with many important features to consider the proper harvesting activities.
T
F
It is important to know if there are borders at the terrain that restrict accessibility.
T
F
Studying the ground surface does not tell the harvesting team anything about carrying capacity and accessibility.
T
F
Site index (“bonitet”) are not so important for planning harvesting operations.
T
F
Vegetation provides indications of the site’s soil type and hydrology.
T
F
Studying the driving tracks created by both the harvester and forwarder provides continuous information about the ground type, carrying capacity and hydrology.
T
F
Bonitet is connected with soil texture and thus the carrying capacity.
T
F
Flat areas or hollows in the terrain are rarely swampy.
