As water tables dissolve limestone, caverns are created and the base level drops. Most caverns are formed by dissolution of the limestone in bedrock. Caverns are in karst or rocky regions and do not always contain entrances.

(Cavern in Suva, Fiji formed by dissolution taking away the limestone.)
Rivers are fluvial processes that cause erosion or deposition on the river beds. Rivers that look muddy are suspended loads which include sediment that is carried in the body of the flow. Since there are pieces of sediment in the water, it is not as clear as dissolved loads.

(Muddy suspended load river going from Nadi to Suva, Fiji)
Fiji has many littoral zones which is from the high water mark to the shore, which is subbmerged in water. In a few areas you can also see tombolos which are depositional landforms that extend from the shore out into the water.

(On this Fiji littoral zone you can see a tombolo which just looks like an extended beach out into the water.)

ated to the right of Australia and is in the Tropic of Capricorn which makes the temperatures and humidity higher year round. The diurnal temperature tends to stay about the same all year because of this location.)
(When Fiji changes fromt he wet to dry season, the temperature stays about the same, only dropping at night.)
(The location of Fiji allows some of the islands to be in the mE air masses and other islands are closer to the mT air masses.)
(This picture shows how the clouds that form in the early mornings in Viti Levu, Fiji. There are only two levels of clouds in this picture. Although the altostratus clouds are higher than the cumulonimbus, they are both reasonably low)
(This picture shows a cyclone that is starting to form over Fiji. You can see where the low pressure system is starting to spin the clouds where a cyclone is likely to form.)
(This picture shows the wind speeds blowing west to east against the trade winds and bringing unusual weather to Fiji. Mostly more wind than usual.)
(Weathering caused these rock formations at Lavena Walk in Taveuni, Fiji Islands. Most people believe that wind and sand usually cause rocks like this, but it is actually from salt breaking off little pieces off the bottom of rocks.)
(This picture is a flood in Nadi, Fiji from 4 days of rain. By the way people describe them, they seem to usually be debris flows like the one above.)
(This rock fall in Viti Levu, Fiji shut down the highway because of its intensity and size)
(This picure of the soil in Suva, Fiji shows the red dirt which is good for farming from the organic parent material. )
