Answer:
<h2>a globe is a round model of the earth. It shows Earth's shape and its lands. A map is a flat drawing of all or part of the earth's surface. Cartographers or mapmakers use complex mathematics to transfer shapes from the round globe to a flat map</h2>
Explanation:
Answer: Its presence is a good determinant of past hot climates. Its absence can also indicate cold climates.
Explanation:
18O and 16O are oxygen Isotopes, and are used in determining past climates. Heavier than the 16O with 10 neutrons and 8 protons, the 18O does not evaporate as easily and because of this, higher amounts are found in the tropics.
Together, they serve as good determinants of past climate by checking for their ratio in fossils.
Also the 18O isotopes are not present in polar regions as they precipitate before getting to higher altitudes. Cold areas, on the other hand, are high in 16O as they get trapped in glaciers. When climate changes in a location, the quantity of both of these oxygen isotopes also changes.
Answer:
It allowed for easier communication.

Answer:
Geographic Information systems
Explanation:
Geographic information systems also known as GIS is used in collecting, storing, manipulating, analyzing geographic and spatial data.
GIS is core and very essential to making geographically oriented decisions. The system works more like a statistical set up but with a touch and edge of being able to handle geographic data perfectly well. This provides a new dimension for business, government etc to make decisions that would serve the need of all.
How it is used:
GIS is made up of different components which helps to make it very unique and special. The system consists of hardware, software and the people ware.
Attributes of features are collected with respect to a study. Their location are also included in the sampling. The software environment which can be a system application or web based one helps to manipulate the data in the best way to produce a fitting result.
