Academic Institution Partnership Hydrogeological Survey of Somalia Despite groundwater being the main source of water for humans, agriculture and livestock, there is neither a hydrogeological map nor a sound policy for groundwater management and exploration in Somalia. SWALIM undertook a quantitative and updated assessment of the groundwater resources of Somaliland and Puntland and the set-up of a system for groundwater level monitoring. Read more Supporting sustainable water resource management The development of new groundwater sources in Somalia is fraught with challenges. Read more Sustainable water use Water is Life! SWALIM project has developed systems for monitoring surface and groundwater in Somalia to support planning, development and sustainable exploitation of the scarce and valuable water resources in the country. SWALIM seeks to strengthen these three dimensions together in order to put in place a viable capability for sustainable water and land resource management within Somali institutions. Up-to-date Information about these resources ensures informed decisions on their management and utilization, subsequently guaranteeing they will remain for the welfare of future generations. Information extracted from satellite images are essential for informed land planning, consistent natural resources assessment, disaster early warning and management, and other tasks.
Relative Age of Rocks

People used to think that Earth was static, and that it never changed. Gradually, a body of evidence was gathered that made no sense in this model. Alfred Wegener, Geologic Supersleuth, laid the groundwork for a whole new theory for the large-scale changing nature of the earth. Background on the Ground Have you ever had the experience where you see a younger relative or friend after not seeing them for a few years, and you’re taken aback at how much they have grown?
Specific Lesson Objectives s: Students will understand how fossils are formed and how they provide evidence of evolution. Students will understand why there are so many gaps in the fossil record, and why there are few fossils of organisms or body parts made of soft tissue. Students will get experience using the Internet. Students need access to Internet using Netscape 4x or Internet Explorer 4.

Stone Tools Ancient Tools Stone tools and other artifacts offer evidence about how early humans made things, how they lived, interacted with their surroundings, and evolved over time. Spanning the past 2. These sites often consist of the accumulated debris from making and using stone tools. Because stone tools are less susceptible to destruction than bones, stone artifacts typically offer the best evidence of where and when early humans lived, their geographic dispersal, and their ability to survive in a variety of habitats.
But since multiple hominin species often existed at the same time, it can be difficult to determine which species made the tools at any given site. Most important is that stone tools provide evidence about the technologies, dexterity, particular kinds of mental skills, and innovations that were within the grasp of early human toolmakers.
Early Stone Age Tools The earliest stone toolmaking developed by at least 2. The Early Stone Age began with the most basic stone implements made by early humans. These Oldowan toolkits include hammerstones, stone cores, and sharp stone flakes. Explore some examples of Early Stone Age tools. Middle Stone Age Tools By , years ago, the pace of innovation in stone technology began to accelerate. Middle Stone Age toolkits included points, which could be hafted on to shafts to make spears; stone awls, which could have been used to perforate hides; and scrapers that were useful in preparing hide, wood, and other materials.
Explore some examples of Middle Stone Age tools.

There are several common radioactive isotopes that are used for dating rocks, artifacts and fossils. The most common is U U is found in many igneous rocks, soil and sediment.
Crustal Tectonic Plates and their movement How the Earth’s crust is split into large sections called tectonic plates is described. Their movement and effects at plate boundaries are explained e. Evidence to support the theory plate tectonic movement Wegener’s theory of continental drift is also described e. Tectonic Plates of the crust and their movement – unstoppable powerful plate tectonics!
Introducing the basic ideas and evidence – see also section 9. What can happen when tectonic plates meet or part The ‘compact’ diagram Fig 2. Plate Tectonics above gives the “2nd Big Picture View” view of plate tectonics and the situations at 1 to 4 will be referred to throughout the answer notes of sections 8. The Earth’s surface is very uneven with all its mountains and valleys and at one time scientists thought this was due to shrinkage of the Earth’s surface crust as it has become cooler over millions of years.
We know this is not true, apart from erosion and the effects of rivers, all the major geological features of the Earth can be explained by the science of plate tectonics. This theory is much better at explaining certain geological events and patterns observed in terms of eg mountain ranges and deep ocean trenches. There were features of the Earth’s geology and fossil record which could not be explained e.
Also, the fact that geographically the continent of Africa seem to fit quite neatly into the shore line of the South America continent.

Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age. Scientists also use direct evidence from observations of the rock layers themselves to help determine the relative age of rock layers. Specific rock formations are indicative of a particular type of environment existing when the rock was being formed. For example, most limestones represent marine environments, whereas, sandstones with ripple marks might indicate a shoreline habitat or a riverbed.
The study and comparison of exposed rock layers or strata in various parts of the earth led scientists in the early 19th century to propose that the rock layers could be correlated from place to place. Locally, physical characteristics of rocks can be compared and correlated. On a larger scale, even between continents, fossil evidence can help in correlating rock layers. The Law of Superposition, which states that in an undisturbed horizontal sequence of rocks, the oldest rock layers will be on the bottom, with successively younger rocks on top of these, helps geologists correlate rock layers around the world.
This also means that fossils found in the lowest levels in a sequence of layered rocks represent the oldest record of life there. By matching partial sequences, the truly oldest layers with fossils can be worked out. By correlating fossils from various parts of the world, scientists are able to give relative ages to particular strata. This is called relative dating.
Relative dating tells scientists if a rock layer is “older” or “younger” than another.

Background on the Ground Have you ever had the experience where you see a younger relative or friend after not seeing them for a few years, and you’re taken aback at how much they have grown? We have an image in our minds as to what they looked like the last time we saw them, and they are much different. If the continents of the earth move and grow, why don’t we notice that?
How Plate Movement Affects Earthquakes, Tsunamis & Volcanic Eruptions
Earthquakes, volcanoes, and tsunamis are all dangerous natural disasters, but they also have something else in common – tectonic plate movement. In this lesson, you’ll see how these seemingly different events actually come from similar geological beginnings. Moving Puzzle Pieces The top layer of Earth is an interesting place. Also known as the ‘crust,’ this thin, solid layer is much more than meets the eye. If Earth were an apple, the skin of that apple could represent the crust in terms of thickness and location.
For example, why might one fossil require the use of radiocarbon dating, the law of superposition (layering), and observations of reversals in Earth’s magnetic field? Following research and discussion, students should choose one geologic dating technique and .
Many of the creatures of the ancient oceans had strange and complex body shapes. What explains their body shapes? Using creatures from the ancient oceans as examples, discuss how a successful body plan may exist virtually unchanged for hundreds of millions of years while others have become extinct. Hypothesize reasons, motivations and explanations for the first sea creatures stepping out of the ocean.
What do you think motivated the first creature to leave the ocean for land? Why do you think scientists study ocean creatures so carefully? What do we learn from the evolution of organisms in the sea?
