seafloor spreading
uplift
question 2

geodetic markers help precisely mark the locations of gps stations, which are critical for measuring tectonic plate motion. which observation would a geologist predict to see for the geodetic markers located at a divergent boundary?
one marker becomes elevated while the other becomes submerged over time.
the markers slide past each other over time.
the markers move apart over time.
the markers move closer together over time.
question 3

what causes seafloor spreading?
magma from convection currents
earthquakes in the earths crust
hurricanes
tsunamis

Explanation:

• For Question 1: Subduction is the process where one lithospheric plate moves under another at convergent boundaries, recycling lithospheric material.
• For Question 2: At divergent boundaries, tectonic plates move apart, so geodetic markers would move apart over time.
• For Question 3: Seafloor spreading is caused by magma rising from convection currents in the mantle, creating new oceanic crust.

Answer:

Question 1: subduction
Question 2: The markers move apart over time.
Question 3: magma from convection currents
