Weathered debris is a result of
a.) frost wedging
b.) oxidation

d.) wind erosion
an ephemeral stream gets most of its water from
a oceans
b other streams
c rain
d floods

I think the correct answer from the choices for the first question is option D. Weathered debris is a result of wind erosion. For the second option, the correct answer would be option C. An ephemeral stream gets most of its water from rain. An ephemeral waterbody is a wetland, spring, stream, river, pond or lake that only exists for a short period following precipitation or snowmelt.
