Hot springs are found:
Correct answer: D. Hydrothermal vents
- A. Homologous organs
- B. Sedimentary rocks
- C. Analogous organs
- D. Hydrothermal vents
Explanation
Hydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones (places on Earth where two tectonic plates move away or towards one another). The cold seawater is heated by hot magma and reemerges to form the vents.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
