Answer:
The answer is: All of the options
Explanation:
These three clues (Ancient life forms preserved as fossils can tell us what organisms existed and where they were. Matching the fossils can show that land masses were once connected, Matching rock type and rock formations can show the way the continents were once attached, Glacial evidence has been found in areas where glaciers could not exits if the continents were in their current location.) can all tell us that continents and landmasses were together at one time. You can do all three to find out the answer.
On a graph of temperature vs. time, it shows pure substances exhibit a sharp boiling point and a sharp melting point as a horizontal flat line wherein the temperature does not change over time up until all the pure substances boiled or melted. The temperature stays stable at 160°C between 4 minutes and 11 minutes. This horizontal flat line part of the graph is normal of a pure substance. The melting point of a solid substance is usually used to specified if the substance is pure. Likewise, the boiling point of a "liquid" substance can be used to specify if the substance is pure as well.
Answer:
I think it is Transduction
