6. Spilling waves: break far from the shore with gentle slopes.
Plunging waves: break on the beach with a moderately steep slope.

7. A wind swell is marked by a short wavelength and high frequency of waves hitting the coast. A ground swell forms when waves have traveled across a greater distance of ocean before hitting the coast. A ground swell has a longer wavelength and the waves hit the coast less frequently.
8. It was out at sea for 36 hours, and then it hit the Queensland coast. From 5am March 20 to 9pm March 21 it went through Queensland and destroyed a lot of home, buildings, farmland, etc.
9. There are three different types of waves: spilling waves, they break far from the shore and are probably the best for swimming at the beach. Plunging waves, they break on beaches with a moderate slope and form a tube, these are good for you if you like to board ride. Surging waves, roll  up the beach instead of breaking onto it.
10. The waves were all calm on the first day and it looked as if there was no problem, but the second day everything changed. The waves were massive and a lot of seaweed and debris had washed up on the beach, the weather was horrible with the grey clouds above and no one on the beach. The cyclone was about 10 kilometres off shore and it was very very windy. The rain came without warning and hit the window of the lifeguard tower like a bullet. The waves were getting even bigger than I imagined and then it hit. The wind was enormous and the rain hurt when it hit you. The next day debris was everywhere and the streets covered in silt.
