Certainly climate effects on weathering is important, but that question
asks how the two types of wethering are related to each other - how
physical weathering speeds up chemical weathering and how chemical
weathering leads to the physical change in size of rock particles.  Good
diagrams should show how breaking of rocks physically creates more surface
area, and how chemical loss of some mnerals from a rock causes the
remaining chemical-resistant crystals to loosen and fall out. Listing
specific minerals as examples will help.

Try making a chart of the three main types we studied: ground moraine,
terminal moraines, and stratified outwash deposits on the top, then list
down the side where they are found, how they form, what is in them, and
their uses. Most of this can be found in your glacial noteguide and in the
text.

A deposit made by a glacier (moraines and stratified outwash layers).
