Identify two situations for which climatic normals might not be accurate to use in determining daily weather.

Climate can determine a lot of things, but it especially determines what kind of plants and animals can live in an area. For example, polar bears need a cold climate. They would be terribly hot and would die quickly in the desert. When climates start to change, animals and plants become endangered.

Winds are generally in the same direction in certain places over the oceans. They have names like the North East Trade winds and Westerlies. These winds are important in climates and were also important to ancient sailing ships which needed the power of the wind to travel.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

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.
