Question: When a force is applied to a body of a rock at plate boundaries, the rock may bend or break. Faults A break in the Earth's lithosphere where one block of rock moves toward, away from, or past another. That result suggests a powerful feedback between the forces that make the topography and the 'push-back' on the system exerted by the topography, they explained. While their model cannot accurately predict when and where earthquakes will occur in the short-term, it can help at better understanding or forecasting earthquakes over longer time spans, Dr. Holt said. The record of an earthquake, a seismogram, as recorded by a seismometer, will be a plot of vibrations versus time. On the seismograph, time is marked at regular intervals, so that we can determine the time of arrival of the first P-wave and the time of arrival of the first S-wave. • Surface waves are produced when earthquake energy reaches the surface of Earth. 2 Features of Earthquakes • Surface waves travel outward from the epicenter. • The earthquake epicenter (EH pih sen tur) is the point on Earth’s surface directly above the earthquake focus.

B. What are earthquakes? are the vibrations in the ground that result from movement along breaks in Earth's lithosphere. 2. The forces that move breaks in the lithosphere. Where do earthquakes occur? 1. Most earthquakes occur along active also push and pull rocks along . These areas are plate boundaries, boundaries, generally in the middle of oceans or along the edges of a. Deep earthquakes occur along where a denser oceanic plate subducts into the mantle. b. A strong burst of shaking occurs during an earthquake. The second longest ever recorded earthquake occurred in 1964 in Alaska and lasted for four minutes (Figure 9.9). Foreshocks are small bursts of shaking that may precede a large earthquake. Foreshocks can occur days before the earthquake hits, or just minutes before. strongly related to lithospheric plate boundaries. This map shows plate boundaries and the global distribution of active volcanoes. (1960–1994). This map shows plate boundaries and the global distribution of earthquake activity (magnitude 4.5+, 1990–1995). Three kinds of differential stress occur. 1  Tensional stress (or extensional stress), which stretches rock; 2  Compressional stress, which squeezes rock; and. 3  Shear stress, which result in slippage and translation.

Answer: earthquakes result when forces push what


Question: Variables and Hypothesis Variables Scientists use an experiment to search for cause and effect relationships in nature. In other words, they design an experiment so that changes to one item cause something else to vary in a predictable way. For example, if you open a faucet. (the independent variable), the quantity of water flowing (dependent variable) changes in response--the water flow increases. The number of dependent variables in an experiment varies, but there is often more than one. Experiments also have controlled variables. Examples. 1  A researcher wants to determine if the color of an office has any effect on worker productivity. In an experiment, one group performs a task in a yellow room while another performs the same task in a blue room. In this example, the color of the office is the independent variable. Researchers want to learn whether listening to fast-paced music helps runners perform better during a marathon. In an experiment, one group of runners listens to fast-paced music while another group listens to slow-paced music. The independent variable is the one the scientist changes during an expert, while the dependent variable is the one the scientist measures to determine the results of the experiment. Controlled variables are ones that could potentially affect the experiment, and the scientist keeps them the same to make the experiment fair. Independent Variable. The variable that the scientist changes during the experiment is the independent variable. Think of the experiment as a cause and effect exercise. The independent variable is the cause factor. For example, to test the hypothesis that a seed needs light to germinate, the independent variable would be whether the seed was left exposed to light or covered with soil. If you hypothesize that Cub Scout pinewood derby cars are faster when the weight is near the rear, the placement of the weight is the independent variable. These changing quantities are called variables, and an experiment usually has three kinds: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. In an experiment there is only one independent variable. As the scientist changes the independent variable, he or she observes what happens. The dependent variable changes in response to the change the scientist makes to the independent variable. The new value of the dependent variable is caused by and depends on the value of the independent variable. (the independent variable), the quantity of water flowing (dependent variable) changes in response--the water flow increases. The number of dependent variables in an experiment varies, but there is often more than one. The independent variable is the one the scientist changes during an expert, while the dependent variable is the one the scientist measures to determine the results of the experiment. The independent variable is the one the scientist changes during an expert, ... Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age. Many people have trouble remembering which is the independent variable and which is the dependent variable. An easy way to remember is to insert the names of the two variables you are using in this sentence in they way that makes the most sense. The hypothesis is worded so that it can be tested in your experiment. Do this by expressing the hypothesis using your. independent variable (the variable you change during your experiment) and your dependent variable (the variable that. changes in response and depends on changes in the independent variable).

Answer: during an experiment what is a independent variable


Question: Hurricane Irma is believed to have unearthed what could be a centuries-old Native American canoe along the Indian River in Florida. The canoe was discovered by photographer Randy Lathrop who happened to be riding his bike along the river. One of the two 40-foot spruce dugout canoes carved in Hoonah by master carver Wayne Price and apprentices Steven Price (Wayne's son), Zack James (Tlél Tooch Tláa.aa) and James Hart (Gooch Éesh) arrives to Bartlett Cove. Around two dozen paddlers made the trip from Hoonah to Glacier Bay in one of three dugout canoes. Each canoe was outfitted with a sail that in the right conditions can push the large vessel up to 8 miles per hour. The first time the canoe went into the water was a very powerful moment. Flat conditions greeted the paddlers, and as they moved out near a couple of miles near Cannery Point two sea otters fed in the kelp bed. The 42-foot dugout was accompanied by two smaller dugouts and the paddlers inside worked in unison to make the canoe glide through the water with surprising speed. Planks could be added along the upper sides of the dugout to increase freeboard and breadth and the canoe could also be equipped with pole masts and leeboard in order to sail. Thus this native boat design was much used throughout the colonial and territorial periods by a culturally diverse population. An 8000-year-old dugout canoe was found by archaeologists in Kuahuqiao, Zhejiang Province, in east China. This is the earliest canoe found in Asia. The Moken, an ethnic group that lives in Myanmar's Mergui Archipelago and the north of Thailand as sea nomads, still builds and uses dugout canoes. Radiocarbon dates that close to 1492 makes it reasonable to infer that a larger island like Grand Turk also had a population of Indians who could have greeted Columbus at the time of his arrival, even if specific evidence for that has yet to be found. Archeological work is ongoing. Following Columbus Classic features of historic Northwest Coast culture include totem poles, large dugout canoes, wooden boxes, elaborate masks decorated in a distinctive art style, and _____. large cedar plank houses An archaeological horizon is best defined as _____. Samoset greeted the Pilgrims in English in March of 1621. He strode into the Pilgrims compound and said, Welcome, Englishmen. The surprised and somewhat apprehensive Standish and Bradford muttered back, Welcome. Canoe. The commissioning of two, 40+ foot dugout canoes resulted in the largest, traditional dugout canoes in Southeast Alaska. The effort was lead by Master Carver Wayne Price, and after nearly a year of carving by a slew of volunteers, the final boats are incredible to behold. The process starts by flattening the top of the spruce log. Columbus did not, though most certainly aware of the countervailing viewpoints. Indians too practiced a form of enslavement and perpetrated their own atrocities against one another. But even if “both sides did it,” one still has to be accountable, especially when Columbus and those who followed arrived as an invading force with the power to prevail.

Answer:
dugout canoes that greeted columbus
