Answer:
C.Plant fossils of the same kind of fernlike plants were found on five continents
The final temperature of the mixture in the coffee cup calorimeter is; 19.467 °C
According to the law of energy conservation:
As such; the heat transfer in the liquid water is equal to heat gained by the ice
Heat transfer by liquid water is therefore;
- DH = 6.02 kJ/mol) = 150 × 4.18 × (T1 - T2)
- 6020 J/mol = 627 × (20 - T2)
However, since 18g of water makes one mole
- 6020 J/mol = 6020/18 = 334.44 J/g.
T2 = 19.467°C

Answer:
Divergent boundary on land
Explanation:
A rift valley is a lowland region that forms where Earth’s tectonic plates move apart (diverge), or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.
Rift valleys are created by tectonic activity and not the process of erosion.
Tectonic plates are huge, rocky slabs of Earth's lithosphere—its crust and upper mantle. Tectonic plates are constantly in motion—shifting against each other in fault zones, falling beneath one another in a process called subduction, crashing against one another at convergent plate boundaries, and tearing apart from each other at divergent plate boundaries.
The most well-known rift valley on Earth is probably the so-called "Great Rift Valley System" which stretches from the Middle East in the north to Mozambique in the south. The area is geologically active, and features volcanoes, hot springs, geysers, and frequent earthquakes.
