What type of lakes are formed due to the action of wind and waves in deserts, resulting in small shallow lakes that may become salt lakes due to excessive evaporation?

Detailed Solution for Test: Lakes - Question 1
Wind deflated lakes are formed due to the deflating action of winds in deserts. These lakes create deep hollows that may reach the water table, allowing water to seep in and form small shallow lakes. Excessive evaporation in these regions can cause these lakes to become salt lakes or Playas. This process is common in arid desert environments.

Which type of lakes are formed by the solvent action of rainwater on limestone, carving out solution hollows?
Detailed Solution for Test: Lakes - Question 5
Karst lakes are formed when rainwater with solvent properties acts on limestone, carving out solution hollows. These hollows may become filled with water, forming karst lakes. Additionally, the collapse of limestone roofs of underground caverns may also result in the exposure of long, narrow karst lakes that were once underground.

Detailed Solution for Test: Lakes - Question 6

Which type of lakes are created when valley glaciers deposit moraine debris across a valley, forming lakes as water accumulates behind the barrier?
Detailed Solution for Test: Lakes - Question 7
Lakes formed by moraine damming of valleys occur when valley glaciers deposit moraine debris, such as rocks and sediment, across a valley. This deposition creates a barrier that traps water, leading to the formation of lakes as water accumulates behind the moraine barrier.
Test: Lakes - Question 8
Save
What type of lakes are created by the action of beavers constructing dams across rivers with timber, mud, and soil?
Detailed Solution for Test: Lakes - Question 8
Lakes made by animals, specifically beavers, are created when these animals live in communities and construct dams across rivers using timber, mud, and soil. These beaver dams are quite permanent and modify the natural environment, making beavers a keystone species in certain ecosystems.
Test: Lakes - Question 9
Save
Which type of lakes are formed due to volcanic explosions, where the top of the volcanic cone is blown off, leaving behind a natural hollow?
Detailed Solution for Test: Lakes - Question 9
Crater and caldera lakes are formed during volcanic explosions when the top of the volcanic cone is blown off, leaving behind a natural hollow called a crater. In some cases, this crater may be enlarged by subsidence into a caldera. These lakes are often found in dormant or extinct volcanoes.
Test: Lakes - Question 10
Save
Which type of lake is characterized by a glacier leaving behind circular hollows in the heads of valleys up in the mountains?
Detailed Solution for Test: Lakes - Question 10
Cirque lakes, also known as tarns, are formed when a glacier on its way down a valley leaves behind circular hollows in the heads of valleys up in the mountains. These over-deepened hollows may be filled with water, creating cirque lakes.
