The height of the sun refers to the angle between the direction of incidence of sunlight and the ground plane, and professionally speaking, the angle of the height of the sun refers to the angle between the sun's rays in a certain place and the tangent of the surface perpendicular to the center of the earth.
2. The time based on the observer's meridian. Sidereal time, true solar time, and flat solar time (see Universal Time and Time Difference) are measured in terms of the time angles of certain real or imaginary reference points on the celestial sphere, which are related to the meridian of the observer. Observers on Earth at different degrees of longitude have different time angles at the same instant.
Thus, each observer has his own time that is different from the others, called local time, which is the time of the meridian where the observer is located. To put it simply, the actual time of observation varies from place to place.
3. Calculation of the angle of solar altitude: when it hits the equator directly, the angle = 90 degrees - the latitude of the place. Angle not at the equator = 90 degrees - (latitude of the place plus or minus direct latitude) If the calculated place is in the same direct hemisphere as the direct hemisphere of the sun, it is subtracted.

Anonymous users2024-02-06The solar altitude angle at noon (h) = 90° - the difference between two latitudes (the latitude of the direct point of the sun and the local latitude, the same subtraction and the difference).
Calculation steps of local time: longitude difference (same subtraction and difference addition) - time difference (longitude difference * 4 minutes) - local time (east plus west minus).
The height of the sun (also known as the angle of solar elevation) is the angle between the direction of incidence of sunlight and the ground plane.

2.It's 116°E in Beijing, it's 120°E in Beijing, it's 120E to the east of 116E, and then it's east-south.
3.The ocean current that passes through eastern Africa is a warm current, and it has a warming and humidifying effect, so there must be a lot of precipitation.
4.The earth hemisphere does not know what it is.
The lack of tundra in the southern hemisphere is a non-zonal phenomenon, isn't that the definition? Taklamakan is a zonal phenomenon from the coast to the inland.
Zonality, which is not well defined, seems to include equatorial to bipolar, coastal to inland, and vertical geographic.
6.The former is the distribution of the sea and the land, and the latter is the location of a specific location.
5.The sun shines from that side of the natural bandwidth, and the snow line doesn't seem to be very accurate, and there are exceptions.
7.I don't know before.
What are the other effects? Climate: Transport and exchange of heat between high and low latitudes, Regulation of global heat distribution, Warming and humidification of warm currents, Cooling and dehumidification of cold currents.
Marine life The confluence of cold and warm currents causes nutrients to rise on the seafloor or coastal upwelling, bringing deep nutrients to the surface and enriching the feed.
Ocean navigation affects the speed, time and economic efficiency of navigation.
Marine pollution increases the scope of pollution and accelerates the spread of pollutants.

Anonymous users2024-02-04There seems to be quite a few typos.
1.Formally, because the transverse waves cannot pass through, it can be proved that there is a transformation of matter here, and there is a Gutenberg interface.
2.It should be the time when Beijing time is not Beijing, but the time of 120 degrees east longitude (Beijing is 116 degrees east longitude). When it is 12 o'clock Beijing time, Beijing time is 11:44 o'clock, and before the local time is 12 o'clock, so the direction of the sun is south-east.
3.Eastern Africa is a plateau with a savannah landscape with lower heat due to higher altitude.
4.You don't know the topic "Floor Ball"?
5.The snow line is higher on the sunny slope and lower on the shady slope. The natural zone is the opposite.
6.The distribution of sea and land refers to the relative position of sea and land, and the position of sea and land tends to be far from the sea.
7 The main driving force of ocean currents is the prevailing wind, which is affected by the shape of the land and the geostrophic deflection force.
Impacts of ocean currents: Climate: 1. Promote heat transport and exchange between high and low latitudes, and regulate global heat distribution; 2. Influence on coastal climate: warm current warms and humidifies, and cold current cools and reduces humidity.
Marine life: where cold and warm currents meet or rise to compensate for the current, there is abundant bait and fish clusters.
Marine pollution: Accelerate the speed of purification and expand the scope of pollution.
Sailing: Sail faster with the current and slower against the current.
Each question is summarized by a large question answer Generally the answers to the big questions have rules The earth should be memorized In fact, my geography grades are very good, and there is no special learning method, but if you want to learn well, you should reach the point where the textbook is memorized like a stream Say a knowledge point, you can reflect where it is in the book What is the layout of that page For example, there is a ** knowledge point in that position Written in that paragraph, you should know in your mind what knowledge points are on that page in addition to that knowledge point Just reach this level Anyway, that's how I do, it's best to communicate with the teacher, ask the teacher to help, and I wish you a good grade.

The day in place A is 10 minutes longer than that in place B, and latitude A is higher than that of B, which is summer in the Northern Hemisphere, and the sun shines directly on the Northern Hemisphere 12-day length 2=sunrise time; 12 + day length 2 = sunset time >>>More
2-3. Select D and A. The shortest distance between two places is the part of the circle that passes through the two places and passes through the center of the earth that is less apart. Airport A and Airport B are just on the same meridian circle, so the shortest route between the two places is to fly along the meridian circle, first fly south to the South Pole with a difference of 120 degrees of latitude, and then fly north to 35°s with a difference of 55 degrees of latitude, with a total difference of 120 + 55 = 175 degrees of latitude; First fly north to the north pole with a difference of 60 degrees of latitude, and then fly south to 35°s with a difference of 125 degrees of latitude, with a total difference of 60 + 125 = 185 degrees of latitude; Both are shorter as compared to the former. >>>More
