Atomic Radii
 increase top to bottom
 down a column the outer electrons are farther from nucleus
 row (period), atomic radius decrease left to right
Ionic Radii
 Size depends on the number of electrons
 cation (removal of e) creates “space” by reducing
electron-electron repulsions (smaller than parent atom)

tectonics
The Earth has significant moment throughout the year due to pressure in the
mantle.
Ocean floor
mid-oceanic ridge allows new seafloor to be pushed up from the mantle
polarity alternates throughout time creating a striping pattern.
The age of the rock is determined by the carbon dating and checked with
magnetic field dating.
Topography of the ocean floor is the way the ground looks. Volcanoes under
water have high topography and the valleys have low topography.
Plate
Boundaries
three types of plate boundaries, classified by motions:
 Divergent boundaries- spreading apart
 Convergent boundaries- Collide
 Transform, or parallel slip, boundaries – Slide past each other

conditions.
Rocks are classified according to their chemical compositions and textures.
Chemical available when the rock was formed
The texture is an indication of the conditions of temperature and pressure
under which the rock formed.
