In general, the probability of flooding decreases when there is an increase in the amount of
Sand sediments are usually more permeable than silt sediments because sand grains are
The downward movement of water through the ground will usually be the greatest when
The cross sections below represent three beakers that were used to test porosity. Beakers A, B, and C each contain a different size of bead. Each beaker holds an equal volume of beads. The amount of water needed to fill the total pore space between the beads in each beaker was measured. Which statement best describes the porosity that was found for these three samples?
Base your answer to the next question on the diagram below, which shows a model of the water cycle. Letters A through F represent some processes of the water cycle. Letter X indicates the top of the underground zone that is saturated with water. The processes of transpiration and evaporation are represented by letters. The processes of transpiration and evaporation are represented by which 2 letters?
The diagram below represents zones within soil and rock. The zones are determined by the kinds of movement or lack of movement of water occurring within them. What is the deepest zone into which water can be pulled by gravity?
The diagram represents three tubes, A, B, and C, each containing an equal volume of uniform-sized spherical beads. The bottom of each tube is covered with a wire screen. XY is a reference line. In which tube would the water infiltrate at the greatest rate?
Which type of sediment sample normally has the greatest permeability rate?
The diagram below shows columns A, B, C, and D that contain different sediments. Equal volumes of water were poured through each column. Which column of sediment retained the most water?
The pattern of magnetic orientation of rocks is similar on both sides of the mid-ocean ridge.
In which part of the river does deposition not happen?
in Jasper national park, in January the precipitation is around 25mm whereas in June it is 100mm
The system undergoes self regulation by changing its form until the balance is restored
In the winter, accumulation usually exceeds ablation, but in the summer ablation exceeds accumulation
It is when the layer of ice moves not only itself but also moves the layer above it, and can slow down movement, and it another reason why ice moves slower on the base and side of a glacier
The properties of individual rock types such as the jointing, bedding and faulting, as well as the permeability of rocks.
Water can seep into carboniferous limestone because it has many joints, which are easily enlarged by solution
They cant occur on level surfaces as the ice remains intact
In high altitude areas, there is more precipitation but also more seasonal variation in temperature, meaning there is more summer melting. Ice sheets develop here under the influence of dynamic valley glaciers. The glaciers occur in places such as the Rocky Mountains and the Himilayas
It can have a significant impact on the melting of snow and ice and the behavior of glacier systems
