"Yes, I have had an agribusiness course," Leslie Turner said as she looked across the large desk. Her new boss was sitting on the other side of that desk, and, frankly, Leslie wondered what was coming next. She had just accepted a summer internship that would begin in a few weeks, but she had no idea of what her assignment would be at Valley Co-op Producers."Do you know anything about marketing, Leslie?" asked the manager."A little, I have studied marketing in some of my classes," answered Leslie nervously, still not sure what she was in for."Well, we’d like you to prepare an analysis of our petroleum marketing program this summer, Leslie. As you know, we have three divisions: animal nutrition, crop inputs, and petroleum products—all managed out of our headquarters here. Although we want you to spend some time working in each division this summer, we’d like you to spend two days each week talking to people, looking at our records, or whatever you else you feel would be helpful, to give us a good idea of where we stand in the petroleum market. Our petroleum sales have leveled off lately, and I think it’s because our equipment is getting old and our service levels have dropped."

Is there any answer choices?

Environmental science studies the interactions between the physical, chemical, and biological components of the environment, including their effects on all types of organisms. earth science (also known as geoscience), is an inclusive term for all sciences related to earth (geology, meteorology, oceanogr maphy, etc).  although environmental and earth science cover essentially the same material, environmental science places greater emphasis on the biological realm, while earth science places greater emphasis on the physical realm.    environmental and earth science study the interactions of four major systems or “spheres” (figure 8.6).  the  geosphere  consists of the core, mantle and crust of the earth.the  atmosphere  contains all of the earth’s air and is divided into troposphere, stratosphere, mesosphere, thermosphere and ionosphere.the  hydrosphere  contains all of the solid, liquid and gaseous water on earth, extending from the depths of the sea to the upper reaches of the troposphere where water is found.  ninety-seven percent of the hydrosphere is found in salty oceans, and the remainder is found as vapor or droplets in the atmosphere and as liquid in ground water, lakes, rivers, glaciers and snowfields.  the  biosphere  is the collection of all earth’s life forms, distributed in major life zones known as biomes:   tundra, boreal forest, temperate deciduous forest, temperate grassland, desert, savannah, tropical rainforest, chaparral, freshwater, and marine.although the four systems have their unique identities, there is substantial interaction between them.  environmental scientists study the effects of events in one sphere on the other spheres. for example, a volcanic eruption in the geosphere may cause profound direct and indirect effects on the hydrosphere, atmosphere and biosphere as follows: example 1 (volcano)    on may 18, 1980, mount saint helens, in the state of washington, erupted.  this event altered the surrounding environment, and provided scientists with an opportunity to study the effects of volcanic eruptions on the geosphere, hydrosphere, atmosphere and biosphere.  such studies are vital because volcanic eruptions will continue to occur, and will have increasing impact on humans as people continue to settle lands closer to dormant volcanoes. the following are but a few of the myriad of interactions resulting from a volcanic 

Ther are many reasons.. is it a multiple choice?
