Please ask for 10 geography questions in the first year of high school, and 10 geography questions i

1. Mercury. 2. A (Coal is formed by plants over a long period of time, and plants need the sun when they grow, so coal is a fixed solar energy, and water energy is also ** and solar radiation energy, but it is not "fixed". )

3. d (Local time is the time that varies depending on the longitude.) The longitude of each place on the same latitude is different, so how can it be the same in local time? ）

4. Polaris altitude angle = local geographic latitude. Therefore, the local geographical latitude is 40°. The North Star is only visible in the Northern Hemisphere, so it is 40°N.

To know the longitude, you have to calculate the local time. The longitude of Greenwich is 0°. Greenwich Mean Time is the time at 0° longitude.

The 0° meridian is 18 o'clock, and the local is 24 o'clock, which means that the local area is 6 hours earlier than Greenwich, the east is early and the west is late, so the local area is east of Greenwich. The local time differs by 1 hour every 15°, so the difference between the local time and Greenwich is 90° (15° times 6 equals 90°). The 0° meridian to the east and 90° is 90°E.

So the geographical coordinates of the place are (40°N, 90°E).

5. What yellow granite, granite, it's too careless.

D. should be selectedLimestone is a sedimentary rock, and sedimentary rock is formed by the action of external forces. Granite and basalt are magmatic rocks, magmatic rocks are formed by cooling and solidification of magma deep underground, magmatic activity is an internal force, marble is metamorphic rock, metamorphic rock is formed under high temperature and high pressure conditions generated by crustal movement or magmatic activity, crustal movement and magmatic activity are both internal forces.

1.The closest planet to the Sun among the eight planets is (Mercury).

2.Among the following energy sources, which can fix a large amount of solar radiation energy, are ( )a coal. This is the transformation of ancient plants by absorbing sunlight. Geothermal is not, geothermal is the energy of the decay of radioactive elements in the Earth's interior.

3.For all places in the same season and on the same parallel, the following statement is incorrect ( ) dThe time is the same everywhere.

Local time varies depending on the longitude.

4.The elevation angle of the North Star is 40° at 24 o'clock in a certain place, and it is 18 o'clock GMT at this time, what are the geographical coordinates of this place? Briefly explain how to calculate.

Latitude is equal to the elevation angle of the North Star as seen locally, so the latitude is 40 degrees north. Greenwich Mean Time is Universal Time, which is 24-18 = 6 hours behind the local time, so it is 6 time zones east of the 0 degree meridian, each spanning 15 degrees of longitude, so the longitude of the place is 90 degrees east. So the local latitude and longitude is 40 degrees north latitude and 90 degrees east longitude.

5.The following rocks formed by external forces are ( ).

a Yellow granite.

1 Mercury 2d, because water energy is actually brought by rainfall, only with solar energy can there be evaporative rain (a is also true, after all, coal is the previous solar energy, is indirect).

3D, local time and meridians.

4 Because the elevation angle is 40 degrees, it is 40 degrees north latitude, and the time is 18 o'clock, so it is 90 degrees east longitude.

5b Basalt (basalt is an ejecta rock, which is formed by mafic magma erupting from the surface, some of which can form stomata or be filled by minerals to form an almond-like structure during the cooling process, and some of which form microcrystals during the cooling process, and may have a large structural gap, but the appearance is dark or dark green, mainly the color of mafic pyroxene, which is called basalt in geology.

The teacher was so annoyed that I was in class, so I was late.

Hello--- answer.

1 x order is from near to far--- water, gold, earth, fire, wood, earth2 a (common mineral energy (coal, oil, natural gas, etc.): as the main energy source of industry, a large amount of solar energy is fixed in these fossil fuels. As for why fossil fuels such as coal and oil fix a lot of solar energy, this is mainly because coal and oil were formed from biological remains in geological history, and the growth of living things needs to absorb a lot of solar radiation energy).

3 d.The time is the same everywhere.

4 a, longitude 90 degrees east, latitude 40 degrees north.

The elevation angle of the North Star is 40 degrees, which means that this location is 40 degrees north latitude, and this location is 24 o'clock GMT at 18 o'clock on the same day, which means that this place is in 6 time zones east of Greenwich (0 time zone), that is, 0°+6*15°=90 °E).

5b Basalt (basalt is an ejecta rock, which is formed by mafic magma erupting from the surface, some of which can form stomata or be filled by minerals to form an almond-like structure during the cooling process, and some of which form microcrystals during the cooling process, and may have a large structural gap, but the appearance is dark or dark green, mainly the color of mafic pyroxene, which is called basalt in geology. ）

Mercury. a Geothermal energy is caused by the decay of elements in the Earth's interior Nuclear energy is nuclear reaction energy d Places are divided according to longitude.

40 degrees north latitude, 90 degrees east longitude A few degrees of elevation is a few degrees north latitude, and when Greenwich Mean Time is 0 degrees longitude, it is 6 hours faster than it is 90 degrees east of it.

Limestone (formed by sedimentation) A and B are formed by the cooling of magma and c by the metamorphism of other rocks at high temperature and pressure.

1. Mercury is from near to far from the sun: water, metal, earth, fire, wood, earth, king, neptune2, a coal and oil are all formed from the remains of living beings in geological history, and the growth of living things needs to absorb a large amount of solar radiation energy.

3. D is the same when the place on the same meridian is the same.

4. The elevation angle of the North Star is 40°, which means that the latitude of the place is 40 degrees north latitude, and the North Star cannot be seen in the Southern Hemisphere; Greenwich Mean Time is 18 o'clock in the Central Time Zone, and the local time is 24 o'clock, the difference between the two is 6 hours, and the time is earlier than the Central Time Zone, so the place is on the east side of the Central Time Zone, according to "the time difference is one hour, and the longitude difference is 15 degrees", the longitude of the place can be obtained to be 90 degrees east longitude. Therefore, the geographical coordinates of the place are 40 degrees north latitude and 90 degrees east longitude.

5. d Granite is an intrusive rock and basalt is an ejecta rock, both of which belong to magmatic rocks and are formed by magmatic action; Marble is a metamorphic rock that is formed by metamorphism; Limestone is a sedimentary rock that was formed by sedimentation.

1.Mercury (Ann Order, Back Bar, Water, Gold, Earth, Earth, Earth, Heaven and Sea) (Coal is changed from plants, and plants fix solar energy through light and action) (It is formed by strong external pressure after the deposition of sand grains).

For a very simple reason, please check the map of the world's ocean currents.

When the North Atlantic Warm Current reaches the Norwegian Sea, the water temperature of this warm current is already very low, for example, it has dropped to a temperature of less than 10 degrees Celsius above 0, but it is still warmer than the surrounding sea water, so it is still a warm current.

Another ocean current, the California Current, began to flow southward from the mid-latitudes (the sea area slightly north of the U.S.-Canada border), and as it moved south, by the time it reached the coast of Mexico, the temperature of the current had risen to more than 10 degrees Celsius, but it was still cooler than the surrounding sea temperature (the surrounding tropical sea, the sea temperature was more than 20 degrees), so it was still a cold current.

Please look at these two examples of ocean currents and you will understand.

Uh......I don't know, maybe it has something to do with latitude or something.

For example, the cold current at low latitudes may be warmer than the warm current at high latitudes, and the cold current at low latitudes should be compared with the warm current at low latitudes.

In fact, you can look at the definition of ocean currents, and I don't know == "If the water temperature of the ocean current is higher than the water temperature that reaches the sea area, it is called a warm current; If the water temperature of the ocean current is lower than the water temperature that reaches the sea area, it is called a cold current. Generally, ocean currents flowing from low latitudes to high latitudes are warm currents, and ocean currents flowing from high latitudes to low latitudes are cold currents. ”

That's probably what it means, and the temperature of the oceans is different

Temperature is heat.

Different latitudes get different amounts of heat.

As long as it flows from high latitudes to low latitudes, it is a cold snap.

On the contrary, it is a warm current.

So if the latitude of the cold snap is lower than the latitude of the warm snap.

Naturally, yes. I'm also talking from memory.

I haven't studied in a few years.

I gave all the knowledge back to the teacher.

Warm and cold currents are also relative. It's as if cold air from the north moves south in the summer, and warm and humid air from the south moves north in the winter. The cold air in the summer is likely to be warmer than the warm air in the winter.

Season: If it is winter in the Southern Hemisphere, compare the warm currents in the Southern Hemisphere to the cold currents in the Northern Hemisphere. It may be so.
