A VOLCANIC LAKE BASIN
If the lava is viscous or if
the vent of the volcano is blocked, eruption will be explosive. Such explosive
top of the volcano, turning it eruption can usually remove the
into a rounded funnel-shaped
hollow which reaches. great depth. In some cases, the hollows are formed by the
subsidence of the collapse or
top, resulting in the cooling contraction of magma. The vent will be finally blocked by solidified lava. In time, water fills the hollow, converting it into a lake called crater lake or caldera lake,
In mountainous areas, snow often collects in the hollows of rocks.
Plucking, a process by which craks and joints are enlarged by freeze and thaw action, takes place, the sides of the hollow are steepened and the base deepened.
The hollow is enlarged into an armchair featu re known as corrie.
d. Warmer conditions cause
ice to waste away, and
moraine to be pushed forward and left on the
lip.
After the ice melts, a lake occupies the corrie or

FORMATION OF
A CRATER LAKE (TARN) C
On the floor of U-shaped valleys, elongated hollows may be carved out by the actions of plucking and abrasion of the glaciers, water will occupy these hollows and convert them into lakes termed ribbon lakes. Sometimes, these long and narrow lakes may be a resuit of the deposition of moraines on the floor of the U-shaped valley. They dam up rivers to form lakes.
