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 and explanation:
a) The plate tectonics is a theory that suggests that Earth's outer shell is divided into several plates that glide over the mantle (rocky inner layer above the core), there are seven major plates that make up 94% of the Earth's surface and many smaller plates making up the other 6% (I annexed a map of those tectonic plates). The tectonic plates are in motion (presumably since the beginning of time), the movement of the plates creates three types of tectonic boundaries:<em> convergent </em>(plates move into one another); <em>divergent </em>(plates move apart); and <em>transform</em> (plates move sideways in relation to each other).
b)The Mid-Atlantic Ridge (MAR) is a divergent tectonic plate or constructive plate boundary located along the floor of the Atlantic Ocean. <em>The MAR developed as a consequence of the divergent motion between the Eurasian and North American, and African and South American Plates</em>
c) In areas where the plates come together, sometimes volcanoes will form, they can also form in the middle of a plate, in places called "hot spots" where magma rises upward until it erupts on the seafloor. The Hawaiian Islands<em> were formed by such a hot spot occurring in the middle of the Pacific Plate.</em>

Answer:
15003.19
Explanation:
The fossil bones age can calculated by using the formula
t = (In ( 12.5 /100) / (-λ)) × half life
where λ = 0.693
t = ((In (12.5 /100) / (-0.693) ) × 5000 = 15003.19 years
the age of the fossil bones is 15003.19
thus the age of the human habitation site 15003.19
Answer:
the greatest environmental impact is increased greenhouse gases.
Explanation:
- The fossil fuel are those elements that release tonnes of carbon dioxide on burning and they lead to the creation of greenhouse gas effect that creates problems for the increasing carbon content and since carbon absorbs much of the solar energy it raised the temperature of the earth and creates visible pollution on land, and water.
