Agricultural scientists.
Some types of
scientists work to improve agriculture.
Crop scientists study the genetic breeding
and management of field crops. Soil sci-
entists use soil physics, soil chemistry,
and soil microbiology to enhance soil fer-
tility and the growth of plants. Agrono-
mists develop practical applications for
discoveries in plant and soil science to
produce high quality food.
Other scientists
. There are many other
branches of science. Geologists study the
history and composition of our planet, in-
cluding volcanoes and earthquakes.
Oceanographers study the oceans and
their movements. Meteorologists study
