Which statements describe how globes represent earth's surface? check all that apply. they are created to scale. they model all or part of earth's surface. they are spherical and three-dimensional. they represent surface features using symbols. they provide detailed information about towns or cities.

Options (1), (2), (3), and (4)

Explanation:

A Globe is usually defined as a three-dimensional spherical model representing the earth and is widely used in understanding the earth's surface as well as the various types of features that are present on it. It is very efficient to use with proper scale because it shows no distortion in terms of shape and size. It shows every portion of the earth, covering all the geographical features that are present on the earth's surface. These features are mostly represented by using different types of colors. The lines of latitudes and longitudes are also prominently drawn.

Thus, the correct answers are options (1), (2), (3), and (4).

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
