Point a and point b are 50 meters apart. the temperature at point a is 60°c. at point b, it is 55°c. the temperature gradient between the points is . keeping other conditions constant, if the mantle and the crust were closer to each other, the temperature gradient between the two would be .

Given:

Temperature at A = 60 C

Temperature at B = 55 C

To determine:

The temperature gradient

Explanation:

Temperature gradient can be expressed as the variation in temperature from one point to the other

Temperature gradient = ΔT/Δd

= (60-55) C/50 m = 0.1 C/m

Ans: Thus the temperature gradient is 0.1 C/m

0.1 c/m and higher

Explanation:

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
