11) As water flows and interacts with rocks that create the parent material in many areas of Minnesota, it can contribute to weathering and erosion. Which of these is NOT a mechanism for how water contributes to the breakdown and movement of rock material due to weathering and erosion? A) Water dissolves minerals embedded in the rock, carrying them away.
B) Water penetrates rock crevices and then expands when it freezes in Minnesota winters.
C)Water carries sediment to a remote location and deposits particles as its flow begins to slow.
D) Water buffers the pH of the landscape, acting as both an acid and a base with its H+ and OH-components.​

Which type of seismic waves are confined at the surface

Scientist: cross-sections of stalactites—calcite formations deposited on cave ceilings by seeping water—can reveal annual variations in rainfall in particular areas over hundreds and thousands of years. we often found that when—according to these cross-sections—drought occurred in a particular area, it coincided with the collapse of an ancient society in that area. i hypothesize that drought reduced agricultural productivity in these areas, thereby leaving these societies without the resources needed to handle internal stresses and external threats. which of the following, if true, would most weaken the support for the scientist's hypothesis? a. many droughts indicated in the cross-sections of stalactites do not correspond with the collapse of a society in that area. b. information from the cross-sections of stalactites alone cannot reveal the level of agricultural output in an area at a particular time. c. most of the societies that collapsed during droughts did so when internal power struggles coincided with military raids from neighboring societies. d. most of the societies that collapsed during droughts maintained large stockpiles of food and water at the time of their collapse. e. information from stalactites also suggests that the collapse of some societies coincided with periods of abnormally high rainfall.

Which of the following statements best describes the quantity theory of inflation? a. inflation occurs because production cost rise and this cost increase is passed on to consumers in the form of higher prices b. inflation occurs because there is too much money in the economy c. inflation occurs because demand of good and services exceeds existing supplies d. none of these
