Presentation transcript:

Geo5: I an apply relative dating concepts to infer the history of a landscape. - Lesson: Memory Blocks - Describe/define/demonstrate the concept of relative dating - Apply geologic principles and laws to determine the relative age of a geologic specimen or event - Infer and describe the sequence of events that formed a landscape - Use observational evidence to determine/support relative ages and/or inferences about geologic events.

Relative Dating Principles - Law of Superposition: in an undeformed sequence of sedimentary rocks, each bed is older than the one above it and younger than the one below

Principle of Cross-cutting Relations: features (faults, intrusions etc.) that extend across a rock layer are younger than that layer.

Principle of Original Horizontality: Layers of sediment are generally deposited in a horizontal position

Geo2 - Radiometric Aging Lesson: Geologic Time: the mid-life crisis of radioactive atoms. Define half life Calculate the half-life of a radioactive atom given the appropriate information Explain how radio-metric dating is modeled and/or used to determine age Determine the age of a specimen given the appropriate information Half Life: the amount of time it takes for half of the parent atoms to decay/transform into the daughter atom

Relative vs. Absolute Aging - Absolute - Determined using radiometric dating - numeric ages - Example: rock A is 500 myo, rock B is 13 myo - Relative - Determined using geologic principles - non-numeric ages ("this" is older than "that") - Example: rock A is older than rock B

What makes your inferences better than mine?

. Geo1: Lesson: Rock Cycle Activity Identify the 5 states of inorganic earthen material Identify and/or define the 5 processes that inorganic earthen material go through Describe the process that forms each type of inorganic earthen material Create a diagram that depicts the rock cycle

Geo1 - Geologic Material Cycle Lesson: Rock Cycle Activity Identify and/or define the 5 physical states of geologic materials Identify and/or define the 5 processes that geologic materials go through Describe the process that results in each physical state of geologic material Apply knowledge of rock cycle to an actual geologic scenario

Geo 12: I can create a geologic timeline that depicts that summarizes geologic changes. Timeline created and events are in the correct order Timeline is proportionally acccurate. Example calculations shown. 4 major geologic periods represented and described (age, climate, landscape, life forms) 4 additional global events and the positions of the continents, on the globe, represented

Why did people think the world was flat? What caused a change in that thinking?

How can we be sure of our location on the planet?

Why do we think the continents were arranged like this?

How do we know the location of these plate boundaries?

Geo11 Lesson: What happens at plate boundaries? classify different plate boundaries and associated geologic features Create a diagram (cross-sectional or overhead) that depicts the interactions of plates at plate boundaries and the associated features. Summarize how the distribution of earthquakes, volcanoes, topographic features and various ages of sea-floor sediment reveal plate tectonics. Identify plate boundary type using geologic data. Support claim with evidence. Create a cross-sectional diagram of an oceanic-oceanic divergent plate boundary. Show elevation changes Are there volcanoes? If so, where? How does seafloor age vary with proximity to the boundary? Is there any seismic activity? If so, at what depths? Create a cross-sectional diagram of a continental-oceanic convergent plate boundary. Show elevation changes Are there volcanoes? If so, where? Is there any seismic activity? Geo9 Provide basic description of the Theory of Plate Tectonics Describe evidence, found along plate boundaries, that support the TPT Describe evidence, found away from plate boundaries, that supports the TPT Use a geologic feature to support a claim about the direction of plate movement.

Geo4 - Mineral Density Lesson: Maxmum and Mineral define density as a substances mass per unit of volume (d=m/V) accurately measure the mass and volume of a solid Calculate the density of a solid. Include proper units. Determine the identity of a substance by measuring its density.
