Answer:
A
Explanation:
The closeness of a city to either land or water will affect the temperature of the city. If a city is closer to water, its temperature will be lower. However, if the city is farther from water, its temperature will be higher. This in contrast to the closeness of a city to land. Therefore, it can be concluded that the city with the greatest temperature is city A.
The heat that remains inside the Earth from its creation and radioactive decay are its main heat sources.
The deep earth receives heat from three main sources: (1) heat left over from the planet's formation and accretion, (2) frictional heating brought on by denser core material sinking to the planet's centre, and (3) heat from radioactive element decay.
The energy produced when unstable atoms decay is known as radioactivity, and it is a substantial contributor to the Earth's heat. The main source are the radioactive isotopes of uranium-235 (235U), uranium-238 (238U), potassium-40 (40K), and thorium-232 (232Th) in the Earth's mantle.

Explanation:
Answer:
Altitude and relief features.
Explanation:
- In Ethiopia, the climate changes mostly with altitudes and stays from hot to arid and to cool in plateaus. As t located near the equator, the country has variations in climate throughout the year.
- There exist various plateaus such as Ethiopian highland and mountainous ranges in the country which is responsible for the different climate of the places.
Fossils help scientists date rocks: True
Sometimes younger rock layers are found beneath older rock layers: True, because it happens with landslides and other causes.
No fossils from the Precambrian era have been found because there were no organisms at the time: False because there were organisims like algae and bacteria, and there are a very small amout of fossils from that era.
The map of Earth has changed over millions of years, but is now set: False
