The answer is 3.012×1022. So now we know the number of atoms in a gram of sand, we've got to figure out how many grains of sand there are in a gram and multiply it by the number of atoms in that same weight. (Pssst, pay attention here) That means that there are 43 quintillion atoms in one grain of sand.

Goryan [66]

I just took the test this would be the correct answer.  

 

In the Precipitation Map of Washington, the dark orange section indicates low rainfall in the region. Using the Shaded Relief Map of Washington, you can tell that this area is flat, possibly a plain. These regions typically don't receive a lot of rain. The Precipitation Map of Washington has areas that are dark purple and dark green. This indicates that they both receive a lot of rainfall every year. If you look at these areas on the Shaded Relief Map of Washington, you can tell that these areas with a lot of rainfall are mountainous.  

On the Precipitation Map of Washington, purple/blue means more rain, and orange/red means less rain. The Shaded Relief Map of Washington shows mountains (brown), valleys, plateaus, and canyons. Areas that are flat are smooth on the map. Areas with steep slopes and mountains look rougher.

Explanation: This was on my feedback from the test as possible answers.

However, land habitats have ample of sunlight available for plants. During early colonization of land habitats, dense forests were not present on land which in turn made even more sunlight available to the land plants of all height. Sunlight is one of the required factors to support plant growth and development.
