responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air. This prevents "convection" since there is no upward vertical movement of the gases and is the reason for the ’anvil-shaped’

The Phoenix Bird Name: Date: Block: Teacher: The phoenix bird is sometimes heard about and referenced in mythology‚ and even popular movies today like Harry Potter. But some don’t know its origin‚ and ancient mythological background. It starts with its symbolism.

In the 19th century‚ Hans Christian Anderson wrote a story about the phoenix. Edith Nesbit

Red Kangaroo: Macropus Rufus The Kangaroo is an endotherm. Endotherms generate heat from their body’s metabolism. So their internal body temperature is independent of the external temperature. Endotherms eat more food than ectotherms. This higher food intake results in an increased level of metabolism‚ which is required to produce heat. The Red Kangaroo inhabits inland plains throughout Australia. They prefer open plains where trees and bushes are scarce. The fur on Kangaroos maintains an insulating

The loss of polar ice over the coming decades will lead to irreversible climate change and alter the face of the planet. The earth as we know it is a unique planet composed of global masses of air‚ land and sea. Each body interacts with each other in unique physical and biochemical ways and minute changes in one mass can lead to irreversible changes to another. Climatology is that scientific endeavour that monitors climate systems to explain loss of polar ice. The variables impacting climate and

Broil is the process of cooking food by cooking it over or under radiant heat. Usually when you think of broiling‚ you think of that setting on your oven where the heat comes only from the top heating element to cook your food. That is broiling. Broiling if most often used to cook meats‚ but also can be used to quickly cook or brown dishes topped with cheese or other toppings. Just be sure to watch your food carefully while broiling as the heat radiating from that top element is extremely hot.
