| Lub npe Particle | Loj Ntau yam | Pob zeb sib sau |
|---|---|---|
| Pob zeb | > 256 hli | Conglomerate los yog Breccia (nyob ntawm qhov sib npaug) |
| Cobble | 64-256 hli | |
| Pebble | 2-64 hli | |
| Xuab zeb | 1/16-2 hli | Sandstone |
Nyob rau hauv txoj kev no, dab tsi yog qhov sib txawv ntawm sediment?
Tom ntej no qhov ntau thiab tsawg ntawm sediments me me, granules yog 2-4 hli, xuab zeb 1/16-2mm, silt 1/256-1/16 hli, thiab qhov tsawg tshaj plaws sediment loj yog av nplaum uas tsawg dua 1/256 ntawm ib millimeter hauv txoj kab uas hla . Sedimentary pob zeb yog tsim nyob rau hauv peb txoj kev los ntawm cov no sib txawv me me sediments.
Ib yam li ntawd, lub pob zeb loj npaum li cas? Hauv geology, pob zeb yog ib pob zeb tawg nrog qhov loj ntau dua 2,000 centimeters (787.4 nyob rau hauv) inch. Cov me me yog hu ua cobbles thiab pebbles. Thaum lub pob zeb yuav me me txaus txav los yog yob manually, lwm tus kuj loj heev.
Ib yam li ntawd, vim li cas thiaj muaj ntau qhov sib txawv ntawm pob zeb?
Pob zeb thiab pob zeb yog qhov sib txawv vim random erosional yam thiab txawv internal structures nyob rau hauv txawv cov ntxhia. Nws siv sijhawm ntau txhiab xyoo rau pob zeb tsim, thiab ntau txhiab xyoo rau lawv yuav tawg.
5 hom pob zeb yog dab tsi?

- Andesite.
- Basalt.
- Dacite.
- Diabase.
- Diorite.
- Gabbro.
- Granite.
- Obsidian.

Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Qhov sib txawv ntawm qhov sib txawv ntawm 97 yog dab tsi?
Teb thiab piav qhia: 9/7 x lub reciprocal = 1. 1 / 9/7 = reciprocal
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
