PPT-Relative Dating & Deforming the Earth’s Crust

Folds Faults and Deformities OH MY Uniformitarianism Geologic processes that occurred in the past can be explained by current geologic processes Erosion and weathering that happens today must have been the same millions of years ago. It occurs between two people in a close relationship The nature of dating violence can be physical emotional or sexual Physical This occurs when a partner is pinched hit shoved slapped punched or kicked PsychologicalEmotional This means threatenin 1 Energy in Deforming Materials energy kinetic energies potential energies elastic strain energy inside work permanent plasticity theory all principle of work and kinetic energy principle of conservation of mechanical Deformation.

Essential Questions:. Earth's Layers. Earth’s Crust. The outer layer of the Earth. Earth’s Layers Vocabulary. Inner core . – a ball of hot solid metal at the center of the earth. Outer core . – liquid layer of metal that surrounds the inner core. Mantle. . – earth’s thickest layer between the outer core and crust made of magma. Relative Dating. To . determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition.. https://. www.youtube.com/watch?v=rQx2wLyagk4. . Essential Question:. How are layers of the Earth different from one another?. Standard:. S6E5a. Compare and contrast the Earth’s crust, mantle, and core including temperature, density, and composition.. The Relationship Spectrum. “Keeping It Real”. 1. Lesson Objective:. The student will be able to identify and define dating. They will identify, analyze, discuss the spectrum healthy and unhealthy relationships as portrayed in the words and actions of others.. Inner Core. Outer Core. Mantle. Crust. The Layers of the Earth. 3. Crust. Thinnest layer; density 3 g/cm. 3. The Earth's . outermost. . layer of the 4 main layers. The crust is typically about . 30-40 km thick beneath continents. Estimating age in the archaeological record is the primary focus of archaeological sciences. Being able to establish a timescale is what sets archaeologists apart from other disciplines. . However. , relative dating techniques are still fundamental to the discipline..
