Faahfaahinta casharka

Natiijada casharka

I can describe evidence of how we know tectonic plates move across the surface of Earth.

Muuji qoraalka

Occurrences of earthquakes and volcanic eruptions suggest Earth’s layers are not static but interact with each other. Evidence, such as rock formations and fossils, supports the idea that the continents were once all joined up. Earth’s crust is broken into pieces known as tectonic plates, which move very, very slowly. Plate tectonics is a scientific theory that explains how tectonic plates move and interact with each other. Plate tectonics help scientists better understand and predict changes to Earth’s surface.

Imtixaannada

1. Lakabka dhulka ee ka kooban inta badan birta (iron) iyo nikkel-ka, isla markaana u jira qaab adag iyo dareere ah, waa kee?
- qolofka (crust)
- dhexda (mantle)
- Jawaabta saxda ah:xudunta (core)
- lithosphere-ka
2. Run ama been? Maanta waa lakabka ugu dhumucda weyn ee dhulka (mantle).
- Jawaabta saxda ah:run
- been
3. Waa kuwee astaamahan hoos ku qoran oo ka caawiya culimada dhulka (geologists) inay ogaadaan da'da iyo habka samaynta dhagaxyada?
- midabka
- cabirka
- Jawaabta saxda ah:muuqaalka crystals-ka
- joogitaanka fossils-ka
4. Lakabka dhulka ee ugu weyn ee mas'uulka ka ah goobta magnetic-ka (magnetic field) waa kee?
- qolofka (crust)
- dhexda (mantle)
- Jawaabta saxda ah:xudunta (core)

1. Waa maxay saxan tectonic (tectonic plate)?
- Jawaabta saxda ah:Waa qayb weyn oo adag oo ka mid ah qolofka dhulka (Earth's crust) iyo qaybta sare ee mantle-ka.
- Waa qayb weyn oo dareere ah oo ka mid ah mantle-ka dhulka.
- Waa qayb yar oo taagan oo ka mid ah qolofka dhulka.
- Waa lakab khafiif ah oo ciid ah oo ku yaal dusha dhulka.
2. Mid ka mid ah aragtiyaha ama fikradaha soo socda ayaa sharxaya dhaqdhaqaaqa dhulka qaaradaha (continental landmasses)?
- Jawaabta saxda ah:dhaqdhaqaaqa qaaradaha (continental drift)
- qolofka badda (oceanic crust)
- wareegga hoose ee dhulka (mantle convection)
- gariirka dhulka (seismic activity)
3. Waa kuwee kuwa soo socda ee ah ilaha ugu muhiimsan ee caddaynta taageeraya aragtida kala-wareegga qaaradaha (continental drift)?
- sawirro dayax-gacmeed
- qaababka cimilada
- Jawaabta saxda ah:fossil iyo qaababka dhagaxa
- qulqulka badaha
4. Run ama been? Taallooyinka tectonic waxay u dhaqaaqaan kaliya sababtoo ah qulqulka kuleylka ee gudaha mantle-ka (mantle).
- run
- Jawaabta saxda ah:been
