Answer: 1) jet streams are like rivers of wind high above in the atmosphere. these slim strips of strong winds have a huge influence on climate as they can push air masses around and affect weather patterns-- they form a bond between hot and cold air
2) lifting along fronts: when air masses interact. lifting also occurs along frontal boundaries as air masses of different temperature and moisture content interact with each other. the lifted air cools and the water vapor condences to form clouds in advance of the surface warm front
3) when the temperature difference between the cold and warm is large, thunderstorms and even tornadoes may form. thunderstorms can form at a cold front or within air masses. at a cold front, air can be forced upard quckly. within an air mass, uneven heating can produce convection and thunderstorms
Answer:
Degree Heating Week (DHW) shows how much heat stress has accumulated in an area over the past 12 weeks (3 months) by adding up any temperature exceeding the bleaching threshold during that time period.
Answer:
Nitrate and phosphate levels rise at a rapid rate
Excessive Plant growth and algal blooms cover the surface of the pond, blocking out sunlight.
Underwater plants begin to die due to lack of photosynthesis, which reduces the amount of dissolved oxygen in the water. Animals also begin to die due to less plants available for food.
Explanation:
Answer:
The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era.
Explanation:
It is based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers.
Answer:
Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each haemoglobin molecule to bind four oxygen molecules. Molecules with more oxygen bound to the heme groups are brighter red.
