This refers to the very colorful Zooxanthellae algae. Coral can only survive in clear water so that the light can hit the surface of the water. It is normally found in waters that are between 64-91 degrees Fahrenheit. There are two different abiotic factors for coral reefs. These factors include nutrients and light.
How many half-lives have passed since the crystal formed? A) 1 B) more than 1 but less than 2 C) more than 2 but less than 3 D) more than 3 Answer: B 4) Which of the following geologic observations would NOT bear directly on working out the sequence of geologic events in an area? A) inclusions of sandstone in a granite pluton B) a well-exposed dike of basalt in sandstone C) an unconformity between a granite and sandstone D) the feldspar and quartz contents of a granite Answer: D 5) The principle of ________ is the concept that ancient life forms evolved in a definite order and therefore their fossils can help determine the geologic ages of strata. A) superposition B) cross-cutting relationships C) fossil succession D) fossil assemblage Answer: C 6) Which of the following is an essential characteristic of an index fossil? A) The organism lived in a very specific environment or two, such as tropical volcanic islands.
The native plants Kelp is important because it provides shelter and food for a lot of sea creatures. Kelp is also used by humans for many products, including toothpaste and ice cream. Kelp also serves as a buffer by absorbing energy from waves before the waves hit the shoreline, protecting many of the sandy beaches along the California coast. Phytoplankton is tiny plant that serves as food for many of the ocean creatures from the smallest of fish to large whales. Some scientists estimate that phytoplankton provide the earth with almost half of its oxygen.
The uplift was surrounded by an epicontinental sea where sediment accumulated in marine margins creating sandstones, siltstones and limestones throughout the Basin. Facies 1 in the carbonate unit consists of 4-34 cm beds of black micrite, matrix supported with less than 5-10% grains making it a mudstone; crystalized shell fragments are present, 2-4 mm bivalve bioclasts and sparse 3-5 cm rugose coral and crinoid fragments; horizontal inclined burrows are
Biology Excursion Question Using data collected on field trip and two named animals, explain the relationship between the distribution and abundance of these two organisms and the abiotic features of the rock platform. There is a close relationship between the abundance and the distribution of organisms living amongst the long reef platform. Abiotic features such as temperature range, salinity, Ph. levels, turbidity, water availability effect the distribution and abundance of aquatic sea creatures living in the area. Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions.
But, when you fertilize your lawn too much, fertilize right before it rains, or if you live on the water, it is easy for left over nitrates and phosphates to trickle their way down into the ground water. And everyone knows that water in our aquifer eventually makes its way into our rivers via springs like 3 Sister’s Springs and King Spring in Crystal River, Fl. Big deal, right? Yes, it really is. Fertilizers in our water make it easier for plankton and algae to grow.
Limestone formed after and on top of the older rocks.” (Archaeological Museum Aruba, 3) While limestone is very common rock on Aruba, a white and black speckled plutonic rock called quartzdiorite is also another prevalent part of the landscape. (Archaeological Museum
Both phytoplankton and zooplankton exhibit cycles of productivity and abundance, the magnitude and duration of these cycles is dependent on several factors and is known as physical and biological coupling. The main categories of these factors are light, water temperature and nutrient availability. The cycles of marine life were displayed in the documentary, “Seasonal Seas” and were divided into spring, summer, autumn, and winter. Beginning with the factors in winter, there is low solar radiation, short days, cold water temperature, low biomass of phytoplankton, frequent storms, and low levels of zooplankton (due to a lack of phytoplankton as food). In the Western Atlantic Coast, Sable Island, nearly 100,000 grey seals come to breed between January and February.
Discuss each of the following physical properties of minerals: crystal form, color, streak, luster, hardness, cleavage, fracture, and specific gravity. What is responsible for the physical properties of minerals? Crystal form – Shape is determined by internal structure of mineral & most aren’t perfect b/c they don’t have enough space to form properly. Color- Least reliable. Streak- Color of a mineral in powdered form.
Post-viewing question Q: What are hydrothermal vents? A: Hydrothermal vents are chimney-like structures on the ocean floor. They spew superheated water full of minerals and nutrients. Segment 3: Classifying Species (8 min.) Description Explore the evidence of diverse animal life in the Burgess Shale, and examine the methods scientists use to classify species.
