c) if, then statement **you chose the correct answer**
explanation:
the hypothesis is an educated guess as to what will happen during your experiment. the hypothesis is often written using the words <u><em>if</em></u> and<em><u> then. </u></em>for example, "if i don't study, then i will fail the test." and since c) is the only answer choice that matches this description, c is the correct answer
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!
Going upward from the surface, it is the point where air ceases to cool with height, and becomes almost completely dry. More formally, the tropopause is the region of the atmosphere where the environmental lapse rate changes from positive, as it behaves in the troposphere, to the stratospheric negative one. Following is the exact definition used by the World Meteorological Organization:
The boundary between the troposphere and the stratosphere, where an abrupt change in lapse rate usually occurs. It is defined as the lowest level at which the lapse rate decreases to 2 °C/km or less, provided that the average lapse rate between this level and all higher levels within 2 km does not exceed 2 °C/km.<span>[1] for example</span>
Answer:
How are radio telescopes used to explore space?
