Mrs. strunk's earth science class used an erosion model to investigate the relationship between the slope of a hill, or incline, and
the amount of soil that washes off of the incline.
the class increased the slope of the incline from 1 to 5. then, they poured 100 ml of water down the incline. finally, they collected
the soil from a tray at the bottom of the incline, dried the soil in an oven, and used a balance to find the mass of the soil. the data
from their study is shown below.
soil washed off incline (9)
slope of incline
based on the graph, more soil is washed away when
a. the soil is made mostly of sand.
b.
the slope of the incline is less steep.
c. there are fewer rocks in the soil.
d.
the slope of the incline is steeper.

Populations of blue-winged warblers, a type of bird, migrate south in the winter and return to canadian breeding grounds in the spring. as global temperatures have increased due to climate change, spring has started arriving in the warbler's breeding grounds earlier in the year, before the warblers return. warblers now arrive at their breeding grounds too late to select ideal nesting sites and to feed on important early-spring food sources how are populations of blue-winged warblers most likely to be affected by the earlier arrival of spring? o a. populations will go extinct since the warblers will stop migrating to breeding grounds. b. populations will be unaffected since most species can quickly adapt to effects of climate change. c. populations will increase since warmer temperatures are generally beneficial to survival, d. populations will decline since individuals will be less likely to successfully reproduce, reset next
