Which does a meandering stream look like?
a.
v-shape
b.
s-shape
c.
y-shape
d.
u-shape

D. S-shape.

Explanation:

A meandering stream is produced when it comes in contact with flat plains with sediments such as fine sand, and mud. As it flows through a single channel, it curves like a snake giving it an S-shape. When the river velocity increases, the outside meanders become eroded. Likewise, when the river velocity is decreased, sediments are deposited on the outside meander.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

tracks, burrows, eggshells, nests, tooth marks, or gastroliths
