5. Average weather recorded over at least a 30 year period (7)
7. ... scale: A means of measuring earthquakes by describing and comparing the damage done, on a scale of 1-12 (8)
8. The day to day conditions of the atmosphere (7)

2. ... :Steep sides and a narrow base. Found at destructive plate boundaries. The mantle that rises has a high viscosity- lava is thick and sticky. Sometimes there are pyroclastic flows which travel down the volcano at high speeds with high temperatures (9, 7)
3. At ... :The air falls towards the ground. Evaporation and precipitation happen. There are clear skies, dry calm weather and heavy rain at equator (4, 8)
4. ... scale: Used to record the strength of Earthquakes and Shockwaves. Info collected on Seismometers. A logarithmis scale. (7)
6. ... occur mostly between 5 and 30 degrees north and south of the equator. Any further from the equator and the water isn't warm enough. They occur in the northern hemisphere (especially in pacific) in late summer and autumn when highest sea temps (8, 6)
9. Circular air movements called cells joined together to form the overall circulation of earths atmosphere (6, 11)
10. ... :Low in height and has gently sloping sides. On constructive plate boundaries and hotspots. Thin lava. No volcanic bombs. Layers of lava. Solid lava layers. Frequent but relatively gentle eruptions (6, 7)
