quadrat sampling and the biodiversity survey showed that Longneck Lagoon has a high ranking for the overall health of the ecosystem. Abiotic factors that affects the distribution and abundance explored were air moisture, leaf litter, light, slope and soil pH. In the aquatic ecosystem, abiotic factors that effect the distribution and abundance was explored through the pH, salinity, turbidity, temperature and dissolved oxygen.…

Mulch around but not on top of the plants, with 3 inches of organic compost. Water well until soil is completely moist and soft.

Science Fair Purpose The purpose of this experiment is to find out which type of soil amplifies side-to-side shaking the most in an earthquake. Hypothesis My hypothesis is that sand will amplify the shaking the most because, liquefaction loosens up the soil which can make buildings slide. Materials To build your shake table, you will need: Packing tape Coffee can lid, or any flat plastic lid with approximately 3/8" lip that can fit under the shake table tray Marbles, or any small balls of the…

wears out rocks and soil. Water erosion occurs on streams,rivers banks, sea shores and seaside cliffs. Usually muddy water is a sign of erosion.Usually water erosion happens during rainfalls, snow melts. Runoffs as well because it helps carry away small materials like soil and rocks. There are also more types of erosion like gully erosion and sheet erosion. Sheet erosion is the removal of of soil in thin layers by raindrops and overland flow. Gully erosion is the removal of soil along the…

terrestrial habitat because they provide the organisms living there with oxygen. Portulaca oleracea L., better known as purslane, is a common weed succulent found in Houston.

This annual succulent can be grow up to about 10 cm and its nutritional content make its edible stems and leaves a widely used addition in European, Asian, and Mediterranean…

The beach has three major parts: beach face, berm and back beach. The area above the water, including the intertidal zone, is known as the beach berm. Beach berm can include vegetation, such as trees, shrubs, or grasses. The most familiar characteristic of a beach berm is its type of sand or rock (Marinebio.net, 2014). Along the backshore, accumulations of wind-blown sand may form sand dunes, and when these are sufficiently stable they become consolidated by a characteristic dune vegetation, for…
