Question
After the effects of and topography have been removed from a gravimeter signal, differences in the magnitude of gravity at different locations may reveal all of the following excepts a. underground ore deposits b. oil and gas deposits c. isostatic adjustments d different rock types Competence in a river system may be defined as: a. the maximum channel size b. the largest particle that can be transported c. the maximum amount of water transported b. the maximum amount of sediment that can be transport Which of these statements is NOT true of S-waves? a. They can travel through solids b. They are shear-type waves. c. They cannot travel through gases. d. they can travel through liquids. Major earthquakes and volcanic eruptions: a. usually occur on the boundaries of plates or at hotspots. b. usually occur at the center of plates. c. prove through their locations that Earth is splitting apart at all plate boundaries. d. occur at divergent plate boundaries and hotspots only The bed load of a river channel includes all of the following except: a. sediment on the bottom of the channel b. material suspended in the water column c. material carried by traction d. material transported by saltation Choose from the following types of faults and answer questions 6, 7, and 8 a. normal dip-slip fault b. reverse dip-slip fault. c. thrust fault d. dextral fault Fault (X) is which specific type of fault? Fault (Z) is which specific type of fault? Fault is which specific type of fault? Mechanical weathering may occur as a result of all of the following except: a. impact and abrasion b. rapid, large temperature changes c oxidation of iron-rich minerals d. frost actionExplanation / Answer
2.b) The largest particle that can be transported
The competence of a river is the maximum particle size that the river can transport.It mainly depends on the velocity of the river flow, If the velocity is more than it can transport larger size of sediments.
3) d)They can travel through liquids
The s-waves( secondary waves) can only travel through solids.They are shear waves.The research of the earth's interior can be done by the s-waves.These waves are formed by earthquakes, volcano eruptions, magma movement in earth's interior, and man-made vibrations are also called ambient vibrations
4) d) Occur at divergent plate boundaries and hot spots only
The major earthquakes and volcano eruptions occur at the divergent plate boundaries as the plate interacts at the edges or boundaries, earthquakes occur due to the disturbance in the tectonics plates
5) c) Material transported by traction
The bedload is referred as the particles in the water which are transported along with the bed.It Is by saltation, rolling, sliding or moving
6 X) Normal dip-slip fault
7) z) Reversal Dip-slip fault
8) Y) Thrust fault
9) a) chemical weathering
The mechanical weathering is the process in which the rocks are broken down into smaller particles by the action of mechanical forces by temperature, pressure and also wind
