Hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. W
hen the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. Which two phases of the water cycle are repeated in this process?
Evaporation occurs when liquid water changes into water vapor (gaseous water or steam). Condensation occurs when water vapor changes back into a liquid (when clouds are formed). Hurricane formation, therefore, depends on the repetition of the processes of evaporation and condensation.
When water turns from a liquid phase in the oceans to gas (water vapor) in the atmosphere, this is called evaporation. When the water vapor (gas ) cools in the cooler upper atmosphere to water droplets (that form clouds), this is called condensation. Evaporation is an endothermic process while condensation is an exothermic process.
Segmentation allows for a greater degree of variety among species
The concept of segmentation relies upon the ability for organisms to duplicate organs and structural elements, such as arms and legs
The ability to divide functions into different portions of the body allows an organism to perform increasingly complex activities and use different segments to perform varying functions
For example, humans consist of heteromeric segmentation, in which each segment differs from another and fulfills a specific role
Homomeric segmentation refers to segments that contain similar elements, such as with the segments in an Errantia, a type of worm
