Which formation occurs when huge blocks of ice driven into the ground by the way of the glacier melt?

When the ice block eventually melts, a depression forms, known as a kettle, and if this fills with water, it is known as a kettle lake (Figure 16.33). A subglacial stream will create its own channel within the ice, and sediments that are being transported and deposited by the stream will build up within that channel.

What is the process of the formation of large sheets of ice called glaciers?

Glaciers begin to form when snow remains in the same area year-round, where enough snow accumulates to transform into ice. Each year, new layers of snow bury and compress the previous layers. This compression forces the snow to re-crystallize, forming grains similar in size and shape to grains of sugar.

When a glacier moves under its own weight it is called what?

basal slip. This type of movement occurs when the weight of the glacier causes grains of ice to partially melt. This melt water collects underneath the glacier and reduces friction. This allows the huge mass of ice to slide easily under the influence of gravity.

What is erosion by waves?

Waves erode sediments from cliffs and shorelines. The sediment in ocean water acts like sandpaper. Over time, they erode the shore. The bigger the waves are and the more sediment they carry, the more erosion they cause (Figure below). Waves erode sediment from sea cliffs.

What are 4 features formed by wave erosion?

Wave energy produces erosional formations such as cliffs, wave cut platforms, sea arches, and sea stacks. When waves reach the shore, they can form deposits such as beaches, spits, and barrier islands. Groins, jetties, breakwaters, and seawalls are structures that protect the shore from breaking waves.

What is not conserved when a wave breaks?

While the total energy (the sum of the energies of the mean motion and of the wave motion) is conserved for a non-dissipative system, the energy of the wave motion is not conserved, since in general there can be an exchange of energy with the mean motion.
