High water pressure If scientists were to notice higher than normal levels of turbidity in a lake, what does this most likely indicate? A. a reduction in phytoplankton in the lake B. an increase in suspended solids in the lake C. an increase in light reaching lower lake depths D. a decrease in bacteria and viruses present in the lake B The Mesozoic is the _____ . a) The “Age of the Dinosaur”; the middle era. b) The “Age of Humans”; the middle era. c) The “Age of Plants”; the first era. d) The “Age of Trilobites”; the last era. Fertilizer is washed from lawns and fields when it rains. How does this fertilizer affect waters downstream? D A. Fertilizer produces larger fish. B. Fertilizer erodes stream banks. C. Fertilizer causes flash flooding. D. Fertilizer encourages algae growth. Cylinder of ice used to study records of climate or atmospheric change over the last 100,000 years.

Which of the following could describe lead? a)gas at 280°C b)liquid at 310°C c)solid at 380°C d)solid at 310°C Fossils Forms when living things die and are buried by sediments. Can be preserved. Radioactive Decay Process a nucleus breaks down giving off radiation. Paleozoic During this era invertebrates develop into vertebrates. Trilobites Extinct hard shelled organism used as an index fossil. Carbon 14 dating Process of determining the absolute age of a biological artifact. Mold Forms when sediment buries an organism, the organism dies and a cavity is formed. Relative Dating Finding the approximate age of rock layers. Petrified Fossils that form when minerals replace the remains, turning it to stone. Rock Carbonized, petrified, molds, cast, and trace are what type of fossils? Fossils occur in a order particular ____________. Eras end with a extinction mass_____________. Trace Fossil formed when something like a footprint is left behind in mud or sand and it hardens to stone. 4.54 billion years How old Earth is Geologist A scientist who studies solid and liquid matter of the Earth. Which would least likely have an impact on global climate changes? A producing energy using hydroelectric plants B producing energy using coal C producing energy using oil D producing energy using natural gas A Precambrian The era in which life is created. Carbonized Fossil formed when organism is pressed between layers of mud or clay and leave a carbon imprint. F Which layer is oldest? Low temperature, high dissolved oxygen and a pH range of 6.5 to 8.5, Would this water be healthy or unhealthy healthy Geological Time Scale A measurement used to describe the timing and relationships between events that have occurred throughout Earth's history. The fossil record gives information about past ______ life & environments. Cast A fossil formed when an animal, plant, or other organism dies, its flesh decays and bones deteriorate due to chemical reactions; minerals gradually enter into the cavity. This usually happens in sand or mud. Which layer is the oldest? E Which is an example of a renewable energy resource? A biomass B coal C gas D oil A Sedimentary Rock makes up _____ 75% of the Earth’s surface. Absolute Dating Finding the exact (numerical) age of rock. Intrusion When igneous rock cuts through sedimentary rock, it is called an _____.
