Answer: The map scale
Explanation: A Map Scale is defined as the ratio of the distance on a map to the distance on the surface the map represents. For example, 1 centimetres on a map represents 10 kilometres on the surface of the Earth. What this means is that for every 1 centimetre you measure on the map, that equates to 10 kilometres on Earth/ real life.
Answer:
For the ones that say use calculator try it. Just pop it in and you get your answer :D
Explanation:
rounding
a. 6.54 = 6.5
if the number is 5 or above round up and drop the numbers to the right of it
if its 4 or under drop the numbers to the right of it
in this case your tenth place is 5 so you drop the four.
follow this formula for the rest
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.
