- true
- a slump is an example of erosion. (true/false)
- a
- Alpine glaciers: a) flow down a mountain slowly or b) spread out as a sheet on flat land
- deposition
- part of erosion process in which sediment is placed in a new location
- b
- a rockslide is a) fast b) medium-fast c) slow d) medium
- acid
- _________ in rainwater causes limestone to dissolve, leaving open spaces, or caves.
- melting
- At an alpine glacier's lower end, _____ can occur.
- c
- a creep is a) fast b) medium-fast c) slow d) medium
- alluvial fan
- A (n) _________ forms when a stream leaves a steep valley and enters flatter land. This causes it to slow down, and carry less sediment. The stream drops some of the sediment, leaving it at the base of the slope.
- b
- a slump is a) fast b) medium-fast c) slow d) medium
- creep
- the slowest form of mass movement is a _______.
- mudflow
- quickly moving downhill flow of soil and rock fragments containing a large amount of water
- meanders
- curves and bends that form twisting, looping patterns in a stream channel are called _________.
- oxbow lake
- An _____ ________ is formed when one of the meanders of a stream is bypassed.
- delta
- A (n) __________ forms when a river enters an ocean and drops some of its sediment near mouth of the river.
- c
- which force plays the biggest part in mass wasting? a) fire b) wind c) gravity d) rainwater
- c
- Glaciers can only exist in places where it is cold enough for water to stay frozen: a) at least 3/4 of the year b) only in the winter c) the whole year d) 1/4 of the year (type letter)
- v
- in high mountains, streams often cut ___ shaped valleys that are narrow and steep walled. (type letter)
- moraine
- deposit of sediment left directly on the ground surface by a retreating glacier
- volcanoes heavy rain
- Mudflows can occur on ______ and after _____ ________. (just space, no comma)
- creep
- the slow downhill movement of weathered rock material
- caverns
- Water that moves underground can form ________. (rockfalls, stream systems, caverns, or alluvial fans)
- flood
- An oxbow lake is formed as the result of a _________. (one word)
- true
- Volcanic ash can be part of a mudflow. (true/false)
- rockslide
- a type of mass wasting in which a large mass of rock slides as a single unit down a slope is a ___________
- mass wasting
- downhill movements of masses of rock and soil
- kettle lake
- bowl shaped depression that was formed by a block of ice from a glacier and then became filled with water
- ice
- As snow in a glacier builds up, its weight presses the snow on the bottom into ______.
- true
- The level of the water table is subject to change. (true/false)
- true
- A floodplain is generally a good area for farming. (true/false)
- ice, water, wind
- the three ways in which weathered rock is eroded are.............(alphabetical order, commas to separate)
- alpine, continental
- What are the two types of glaciers, in formation alpha? (don't put "glacier" at the end) ( commas to separate, no "and")
- falls melts
- A glacier forms in a region where more snow _______ than ________ each year. (just space)
- c
- can mass wasting occur a) suddenly, b) gradually, or c) either? (type letter
- mudflow
- a (n)________ occurs when soil becomes so heavy with water after heavy rains, that the slope can no longer hold it in place. A mixture of soul, water, and debris flows downward, picking up sediments along the way.
- mudflow
- a (n)______ can occur after the heat released after the eruption of a volcano causes ice and snow to melt, releasing a large amount of water mixed with ash from the volcano. this mixture rushes down the volcano and picks up debris.
- a
- does soil move as a) a single unit, or b) individual parts in a slump? (type a or b)
- ground moraine
- blanket of till that a glacier deposits along its bottom
- mountains
- mass wasting of rock often takes place in _________.
- divides
- ___________ are lines of high land
- True
- Continental glaciers can cover entire continents. (True/false) (hard one isn't it)
- rockfall
- a type of mass wasting in which a block of rock drop suddenly and fall freely down a cliff or steep mountainside is a ___________
- alluvial fan
- fan shaped deposit of sediment at the base of a mountain
- a
- a rockfall is a) fast b) medium-fast c) slow d) medium
- divide
- ridge from which water drains to one side or the other
- delta
- area of land formed by the buildup of sediment at the end, or mouth, of a river
- lateral moraines
- ridges of till deposited at the sides of a glacier
- dome
- Continental glaciers are shaped like a _________.
