21Molten rock at Earth's surface has this name.RECALL
22This volcano type has broad, gentle slopes built mainly by fluid lava flows.RECALL
23This steep-sided volcano type is built from layers of lava and fragmented volcanic material.RECALL
24This process breaks down rock in place, without transporting the fragments.RECALL
25This process removes and transports rock or soil by water, wind, ice or gravity.RECALL
26This process lays down sediment previously carried by water, wind or ice.RECALL
27This cycle moves carbon between the atmosphere, oceans, organisms and rocks.RECALL
28Glacial erosion commonly produces this valley profile with a broad floor and steep sides.RECALL

48This phase change takes liquid water from a surface into the air as vapour.RECALL
49This phase change turns water vapour into liquid droplets.RECALL
50Rain, snow and hail are forms of this water falling from the atmosphere.RECALL
51This permeable underground layer stores and transmits groundwater.RECALL
52This drainage area directs water toward a common outlet; it is also called a catchment.RECALL
53This atmospheric layer contains most weather.RECALL
54This atmospheric layer contains most ozone.RECALL
55This category of atmospheric gas absorbs and emits infrared radiation, contributing to warming.RECALL
56This climate pattern involves unusually warm surface water in the central and eastern equatorial Pacific.RECALL
57This seasonal wind system reverses direction and often brings a distinct wet season.RECALL
58This organized rotating storm system forms over warm tropical seas around a low-pressure centre.RECALL
