Explanation:
The reasons that islands formed are still growing is simply because newer materials are being added to them.
- A growing earth is as a result of addition of more materials arising from the mantle.
- Generally, Volcanic islands forms as a result of magma that reaches the surface or ocean floor from deeper part of the earth.
- This usually occurs in places around a plate boundary where materials upwells from the asthenosphere or shallow crustal melting.
- As more materials are being melted, more also reaches the surface and continues to make the Island grow.

Answer:
Option A. The specific heat is 0.897 J/gºC, The Substance is aluminum.
Explanation:
We'll begin by calculating the change in temperature of the substance. This can be obtained as follow:
Initial temperature (T₁) = 20.0 °C
Final temperature (T₂) = 40.0 °C
Change in temperature (ΔT) =?
ΔT = T₂ – T₁
ΔT = 40 – 20
ΔT = 20 °C
Finally, we shall determine the specific heat capacity of the substance. This can be obtained as follow:
Mass (M) = 136 g
Change in temperature (ΔT) = 20 °C
Heat (Q) absorbed = 2440 J
Specific heat capacity (C) =?
Q = MCΔT
2440 = 136 × C × 20
2440 = 2720 × C
Divide both side by 2720
C = 2440 / 2720
C = 0.897 J/gºC
Comparing the specific heat capacity (i.e 0.897 J/gºC) of the substance with those in the table above, the substance is Aluminum.
Thus, option A gives the correct answer to the question.
