Answer:
Eurasia
Neanderthals inhabited Eurasia from the Atlantic regions of Europe eastward to Central Asia, from as far north as present-day Belgium and as far south as the Mediterranean and southwest Asia. Similar archaic human populations lived at the same time in eastern Asia and in Africa.
Answer:
A one-step conversion is not sufficient to convert a temperature in the Celcius scale to the Fahrenheit scale.
Explanation:
Hello!
To convert a temperature in the Celcius scale to the Kelvin scale we required just one-step conversion, because we consider that the first scale derives from the second scale.
Celcius scale begins at 0 degrees (0°C), wich coincides with the melting point of the ice, and ends at 100 degrees (100 °C) with the point of water boiling point.
Fahrenheit scale determines that the freezing point of water is located at 32 degrees (32°F) and its boiling point at 212 degrees (212°F). This situation causes a 180 degree interval between the two points.
For this reason, to calculate how many Fahrenheit degrees has a certain temperature expressed in Celcius degrees, we have to multiply the X degrees Celcius (°C) by 1.8, and then add 32 to the previously obtained result.
°F= (X°C x 1.8) + 32

Answer:
The Precambrian history of Earth is difficult to determine for all of the following reasons except e. There are few useful index fossils in the Precambrian record .
Explanation:
Precambrian history
Precambrian history is difficult to study as there are relatively low Precambrian fossils and most of the Precambrian rocks have metamorphosed and ,
there are few useful index fossils in Precambrian record as it is well known the evolution of life on earth was not very predominant in Precambrian time.
Answer:
Option B.
Explanation:
The mineralogy of previously existing rocks changes, is the right answer.
Chemical weathering is generated by rainwater responding with the mineral fragments in rocks to produce new crystals and water-soluble salts. These reflections transpire expressly when the water is imperceptibly acidic.
These chemical processes require water, and transpire more immediately at higher warmth, so hot, humid atmospheres are best. Chemical weathering (particularly oxidation and hydrolysis) is the initial stage in the creation of soils. During chemical weathering, the mineralogy of previously existing rocks changes.
