The atmosphere transfers heat energy and moisture across the Earth. Incoming solar radiation (insolation) is redistributed from areas in which there is a surplus of heat (the equator) to areas where there is a heat deficit (the North and South Pole). This is achieved through a series of atmospheric cells: the Hadley cell, the Ferrel cell and the Polar cell (Figure 2). These operate in a similar way to, and indeed interact with, the ocean conveyor.
For example, as the oceans at low latitudes are heated, water evaporates and is transported poleward as water vapour. This warm air eventually cools and subsides. Changes in temperature and CO2 concentrations can lead to: changes in the size of atmospheric cells (in particular, the Hadley cell is susceptible to these alterations); warming in the troposphere; and disproportionately strong warming in Arctic regions. The strong interactions between ocean and atmospheric dynamics, and the significant feedback mechanisms between them, mean that climate researchers must consider these Earth components as interlinked systems. The necessity to assess ocean-atmospheric changes at the global scale has implications for the way in which research is conducted. It is only by integrating palaeo evidence of past changes, with present day monitoring, and projected models,
A. True. Meiosis and mitosis are the same, right?
Answer:
b. carb (sugars)
Explanation:
plants make glucose through photosynthesis
The right matches are :
A. bryophyte ==> 3.
B. pteridophyte ==> 2.
C. gymnosperm ==> 1.
D. angiosperm ==> 4.
These four types of plants are cormophytes.
Bryophyte is a terrestrial plant belonging to the family Bryophyta, which does not have a real vascular system.
Gymnosperms are the first order of didynamy containing phanerogamous plants whose eggs are not enclosed in closed carpels.
Angiosperms are plants whose seeds are enclosed in a closed ovary.
Pteridophytes produce neither flowers nor seeds but are vascular plants.
After the Big Bang happened, the universe is constantly expanding. The Universe has expanded for around 13.7 billion years. The further a galaxy is, the faster it would move away from Earth. This principle is called the conservation of momentum.
