Figure 1 below shows the temperature distribution of water in the south pacific part of the normal year and 2 in the south pacific part at the time of the el niño phenomenon. The analysis was followed by an answer as requested. (10 minutes)
(1) completion of circulation of the two maps (on-line display of arrows)。
(2) according to the graph, in normal years, whether there is more or less precipitation in eastern australian waters? This is due to the temperature of the surface water and the prevailing current。
(3) according to the graph, the cause of the increase in compensation flows in the western south american seas in normal years is:
。
(4) at the time of the “el niño”, peru's west bank waters were affected by a reverse equatorial flow, and the sea's surface water temperature was likely to prevail, and precipitation would increase or decrease。
Midterm examination for the first semester of the 2006 - 2007 academic year in the city of flat city
16. (three points per space) i and ii sub-issues are selected only for one, if both. Only on question i。
I. Fresh air, clean drinking water and balanced nutrition are all closely linked to human health。
(1) fresh air is a mixture (select “purified” or “mixed”)。
(2) clean drinking water has been purified, and activated carbon is commonly used in the water purification process to adsorb pigmentation and odor。
(3) balanced nutrition requires a reasonable diet. The main organic nutrients in food are sugar, fat, protein, vitamins, and vitamins, which are supplemented by fruits and vegetables。
Ii. Food security and food production are of great concern to the entire population。
(1) a process of chemical change in sulphur dioxide fumigation, ginger, etc. Resulting from sulphur combustion by illegal merchants (check in “physical changes” or “chemical changes”)。
(2) crop growth has certain requirements for soil alkalinity, which is commonly determined by ph paper。
(3) rationally applied fertilizers can increase food production. Commonly used fertilizers are k2so4, co(nh2)2, ca(h2po4)2, among them co(nh2) or urea。
(three points) ten top-class national treasures, such as the qin emperor's bronze horse, the bronze cricket crane, and the under-street map, gathered at the “sian park 2011”。
(1) there was some copper rust on the surface when the qin emperor's copper horse came out of the ground, the main component of which was copper alkaline carbonate. In addition to oxygen- and water-related copper rust, chemical-style findings from alkaline copper carbonate are also related to co2 or co2 in air。
(2) the main component of the copper crane is copper alloy. Generally, alloys change their performance compared to the pure metals that make up them, one of which is the increase in hardness or decrease in melting points。
(3) the main material in the under-tree women's map contains natural fibres, which are used in modern times in addition to natural fibres. The chemical method used to identify natural and synthetic fibres is the burning method。
32. The following description of the inner circle structure of the earth is correct: ( )
A. The rock collage consists of the crust and the entire mantle
The silicon aluminium layer is a continuous circle
