cold, dry cold, wet warm, dry warm, wet |
Warm Wet
|
|
|
A soil's texture is determined by its
water content mineral composition thickness particle sizes |
Particle Sizes
|
|
|
Organic material in soil is also referred to as
humus regolith talus loam |
Humus
|
|

Which of the following does NOT usually trigger mass movements?
growth of native vegetation on slopes. formation of over steepened slopes. saturation of surface materials with water. vibration of the ground during an earthquake. |
Growth of native vegetation on slopes
|
|
|
The energy for the water cycle comes from the
ocean sun atmosphere soil |

|
|
|
How does water move from the plants to the atmosphere?
infiltration precipitation transpiration condensation |
Transpiration
|
|
|
By what process do streams and rivers move materials?
weathering infiltration mass wasting erosion |
Erosion
|
|
|
When do streams and rivers deposit sediment?
when their velocity decreases when they are in the midst of flooding when their velocity increases when they plunge over waterfalls |
When their velocity decreases
|
|

|
|
The maximum slope or steepness at which loose material remains stable is referred to as the
angle of repose angle of reflection normal angle critical angle |

The Hubbard Brook Experimental Forest was used to study
landslides in the forest soil forming factors water and nutrient cycling frost wedging in the forest |
Water and Nutrient Cycle

In the weathering process of pressure-release fracturing
salts crystallize in cracks enlarging fractures. bedrock minerals decompose to clay. bedrock expands and fractures when the overlying rock erodes away. bedrock dissolves and ground water carries the dissolved ions away. |
bedrock expands and fractures when the overlying rock erodes away
|
|

The hydrologic (water) cycle
describes the circulation of water in streams, lakes and wetlands. describes a primary mechanism of the movement of energy as well as the movement of water from one part of the globe to another. describes a primary mechanism of the movement of energy from one part of the globe to another. describes the movement of water from the atmosphere to the hydrosphere. |
