This is tricky to explain simpler since it is already simplified as much as possible, just remember that all landforms are created by erosion or deposition. Both processes happen at the same time, but one always happens more than the other.
Here are the landforms you need to learn and the parts in the textbooks you have to read up on and the relevant animation. I can improve on the information,but you all will need to feedback to me.
Cliff
Page 142, 2nd paragraph to page 143, 1st paragraph (remember how to draw diagram A to D)
Animation: http://www.curriculumbits.com/prodimages/details/geography/cliffs-and-wave-cut-platforms.html
Headland & bays
Page 144, 2nd paragraph
Animation: http://www.wiley.com/college/strahler/0471480533/animations/ch19_animations/animation2.html
Under headland and bays, remember that soft rock erodes first before hard rock. You will also need to know about refraction, under the animation, right at the end you will see how refraction occurs.
Beaches
Refer to my previous post on waves and the animation to see how beaches are formed.
Spits and tombolos
For spit, page 147, 1st paragraph from 2ns line to the word before "(fig 7.20)"
Remember to draw the 1st and 2nd drawing of how spits are formed. Remember that a spit is formed through the process of longshore drift.
The 3rd picture is for tombolo!
The last paragraph and 3rd picture should be added in if you are explaining tombolo. A tombolo is when a spit meets an island and fuses together. I will get the picture from East Coast Park soon, busy with my kids who just came back from Australia! =p
Here is the animation for a spit:
