In addition to writing one blog post, you will also read and comment on one of your peers’ blogs. Your original blog post and peer responses are to be no more than 300 words and included a title. You will be given a grade for your posts and peer responses each week.
You are encouraged to use images and videos to enhance your blog but ensure that proper citation and credit is given to the owners of the images and other materials used if you are not the original author.
Review the
Blog Instructions
before beginning your weekly postings.
Starting in Module 2, you will be required to write one blog post every other week. The blog post on current events that deal with one of the learning objectives of the module for that week. The information for the blog can be from:
- newspapers,magazines,
- the news
research papers, etc.
In addition to writing one blog post, you will also be required to read and comment on one of your peers’ blog posts. Original blog posts and responses are to be no more than 300 words. You will be given a grade for your posts each week.

- Chapter 13 Review QuestionsWhat is a beach? It is the strip of land that separates the ocean from the inland areas. In short, this is where the ocean interacts with the land. Beaches play an important, role because they act as a buffer against higher winds and coastal communities and ecosystems. Watch the video How the Coast Works (9:25 mins)Beaches are also great touristic attractions because of their beauty and some beaches are used as breeding grounds by some ocean organisms like sea turtles.An idealized cross-section of a wave-dominated beach system consisting of the swash zone which contains the subaerial or ‘dry’ beach (runnel, berm, and beach face) and is dominated by swash processes; the energetic surf zone (bars and channels) with its breaking waves and surf zone currents; and the nearshore zone extending out to wave base where waves shoal building a concave upward slope.© 2012 Nature Education Reprinted with permission from Short & Woodroffe 2009. All rights reserved.Types of BeachesThere are many different types of beaches depending on the material that the beach is made up of. Here some of the major types of beaches:Sandy Beaches. (Depending on the color of the sand, it can Red, Green, orange, black, etc.)Seashell Beaches.Glass Beach.Rocky Beaches.Cave Beaches.Urban Beaches.Some of the landforms of beach erosion and beach depositionWhen ocean water interacts with the beach depending on the type of beach erosional and depositional features are produced. To learn more watch the following video What Coastal Landforms are formed by Deposition? (7:44 mins)The diagram below shows some of the major depositional features found on beaches. These are mostly made out of sand and in some cases may contain varying amounts of silt and mud. You can read more by clicking here:Depositional features are found on beaches where deposition is dominant over erosion and there are usually coastlines that are not rocky. On the other hand, rocky coastlines are dominated by erosion. With time the cliff face is transformed into different erosional features as shown by the diagram below.

What Causes Changes in sea level to rise or fall?There is more to sea-level changes than the melting of ice: To learn more about sea level change watch the following video Sea level rise is so much more than melting ice (6.08)Here are some of the major cause of sea level rise:Thermal expansion of water (as water gets hotter it expand)Melting of ice caps Global warmingWatch the following videos paying close attention because the videos will simplify some of the concepts for you and enhance your comprehension. 1.
