Answer
Feldspar a common mineral found in rocks have two cleavage plane and can be cleaved in two directions nearly at right angle . Mica is a group of sheet silica that have perfect basal cleavage plane, and can be cleaved only in one direction.
Fossil record- species evolve differently in different environments . different species evolve similarly in the same type of environment
homologous structures of living organisms- 2 variations; similar body structures that don't necessarily have similar functions
homologous- diff mature forms but develop from embryonic tissues
vestigial- similar structures with reduced size and lesser or no functions
embryology- early stages of many animals are very similar- suggesting that organisms share common ancestry
The study is either Climatology or Meteorology
