The barycenter is always nearer to the more massive object. The barycenter of the Earth and moon is approximately found 1710 mi. inside Earth. 9/25/2014created by: R.E. Angat17
What is Precession? Earth’s axis rotation Earth precessionnutation Remember: Earth’s axis is only an imaginary line. 9/25/2014created by: R.E. Angat18
What is the orbital tilt of Earth? Earth’s orbital tilt is 23.5 degrees. This tilt is responsible for the seasons on Earth. 9/25/2014created by: R.E. Angat19
What are the two factors that causes the precession of Earth? 1. Earth’s shape is oblate spheroid. The spinning motion of Earth causes it to bulge at the equator. 9/25/2014created by: R.E. Angat20
Uneven gravitational pull Precession happens because moon’s orbit is tilted from the Earth’s elliptical plane 9/25/2014created by: R.E. Angat21

9. How are rocks recycled? Rocks are recycled when they are broken by weathering and/or melted by magma when they are buried deep underground. Depending on the process that happens next, a new rock is formed. 9/25/2014created by: R.E. Angat38
Rocks are classified on how they were formed and what type of minerals is present in them. 1. Igneous – melting and cooling. 2. Sedimentary- sedimentation, compaction, cementation, lithification. 3. Metamorphic – heat and pressure 10. How are rocks classified? 9/25/2014created by: R.E. Angat39
