1. Define the following types of waterfalls and give one example of each.

a. Block

In a block waterfall, water descends from a relatively wide stream or river.

Agua Azul - Chiapas, Mexico
Millstream Falls - Queensland, Australia
Niagara Falls - Ontario, Canada

b. Cascade

In a cascade waterfall, water descends a series of rock steps.

c. Horsetail

In a horsetail waterfall, descending water maintains some contact with bedrock.

d. Plunge

In a plunge waterfall, water descends vertically, losing contact with the bedrock surface.

e. Segmented

In a segmented waterfall, distinctly separate flows of water form as it descends.

f. Tiered

In a tiered waterfall, water drops in a series of distinct steps or falls.

To do:
Add galleries for all types listed

2. Choose 10 waterfalls, including 2 from near the area or state in which you live, and list the following information about them: Name, Total Height, Waterfall Type, Watercourse, Location.

3. Complete two of the following activities.

a. Visit a waterfall and write a paragraph telling about your experience.

b. Choose a waterfall (other than ones in #2) of interest to you and record facts and interesting information about the falls that you have selected.

c. Watch a video about a waterfall.

d. Make a scrapbook about waterfalls. Include pictures of waterfalls and important information about each one. This may be a group project.

e. Using the information provided, create a crossword or word search puzzle:

Angel/Tallest waterfall in the world at 3212 feet.
Browne/Tallest waterfall in New Zealand.
Dettifoss/Waterfall flowing from a glacier in Iceland.
Havasu/Waterfall on an Indian reservation in Arizona.

+===b. Cascade===
-[[Image:Iguacu-004.jpg|upright|thumb|[[Iguazu Falls]] in [[Brazil]].]]
+In a cascade waterfall, water descends a series of rock steps.
-A '''waterfall''' is usually a [[geology|geological]] [[geologic formation|formation]] resulting from water, often in the form of a [[stream]], flowing over an [[erosion]]-resistant rock formation that forms a sudden break in elevation or [[nickpoint]].
-Some waterfalls form in [[mountain]] environments where the [[erosion|erosive water force]] is high and stream courses may be subject to sudden and catastrophic change. In such cases, the waterfall may not be the end product of many years of water action over a region, but rather the result of relatively sudden geological processes such as [[landslide]]s, [[Geologic fault|fault]]s or [[volcano|volcanic action]].
+===c. Horsetail===
+In a horsetail waterfall, descending water maintains some contact with bedrock.
-Waterfalls may also be artificial, and they are sometimes created as [[garden]] and [[landscape]] ornaments.
+===d. Plunge===
+In a plunge waterfall, water descends vertically, losing contact with the bedrock surface.

+===e. Segmented===
-[[Image:Waterfall formation23.png|thumb|350px|right|Formation of a waterfall]]
+In a segmented waterfall, distinctly separate flows of water form as it descends.
-Typically, a river flows over a large step in the rocks which may have been formed by a fault line. Over a period of years, the edges of this shelf will gradually break away and the waterfall will steadily retreat upstream, creating a [[gorge]] of recession. Often, the rock [[stratum]] just below the more resistant shelf will be of a softer type, meaning undercutting, due to splashback, will occur here to form a shallow cave-like formation known as a [[rock shelter]] or plunge pool under and behind the waterfall. Eventually, the [[outcrop]]ping, more resistant cap rock will collapse under pressure to add blocks of rock to the base of the waterfall. These blocks of rock are then broken down into smaller boulders by [[attrition]] as they collide with each other, and they also erode the base of the waterfall by [[abrasion]], creating a deep [[plunge pool]].
-Streams become wider and more shallow just above waterfalls due to flowing over the rock shelf, and there is usually a deep pool just below the waterfall because of the [[kinetic energy]] of the water hitting the bottom.
+===f. Tiered===
+In a tiered waterfall, water drops in a series of distinct steps or falls.
+{{Todo|Add galleries for all types listed}}
-Waterfalls can occur along the edge of [[glacial trough]], whereby a stream or river flowing into a [[glacier]] continues to flow into a valley after the [[glacier]] has receded or melted.  The large waterfalls in [[Yosemite Valley]] are examples of this phenomenon. The rivers are flowing from [[hanging valley]]s.
