Question

When first formed the early earth was very hot. Its surface temperature was:

• A. ${1000}^o-{1200}^{o}C$
• B. ${3500}^o-{4000}^{o}C$
• C. ${5000}^o-{6000}^{o}C$
• D. ${8000}^o-{10000}^{o}C$

Answer 1

The correct option is C ${5000}^o-{6000}^{o}C$

The components of the earth are crust (outer part), mantle (middle part) and core (inner part). The crust is the surface of the earth.

Thus the correct answer is option C.
