1. a series of connected mountains close to each other geographically or of common origin
2. the border between two tectonic plates
3. a high, large mass of earth and rock that rises above the earths surface with steep or sloping sides

from the reading collision zones and mountains

1. when two continental plates collide, they are lighter and less dense than oceanic rock so they crunch, fold, and lift the rock up forming and.

click next. you should be on the page labeled divergent boundaries-spreading plates.

1. at divergent boundaries, tectonic plates are moving from each other.

seafloor spreading

1. divergent boundaries in the middle of the ocean contribute to. as the oceanic plates pull apart, a in the ocean floor appears. then comes up from the mantle to fill in the space between the plates. this forms a raised ridge called the. the magma also spreads outward which forms new ocean and new oceanic.

rifts

1. when two continental plates diverge, a develops. this is a dropped zone where the plates are pulling apart. as the crust widens and thins, and form in and around the area. early in the rift formation, and can flow into the low valleys and long, narrow can be created.

Explanation:

Based on geological knowledge and the context of plate tectonics:

• For question 27, when continental plates collide, they form mountains and mountain ranges due to the crunching, folding, and lifting of rocks.
• For question 28, at divergent boundaries, tectonic plates move apart from each other.
• For question 29, divergent boundaries in the ocean contribute to seafloor spreading. A crack appears, magma fills the space forming a mid - ocean ridge, and new ocean crust is created.
• For question 30, when continental plates diverge, a rift develops. As the crust widens and thins, faults and volcanoes form. Early in rift formation, lakes and long, narrow seas can be created.

Answer:

1. mountains; mountain ranges
2. apart
3. seafloor spreading; crack; Magma; mid - ocean ridge; crust; crust
4. rift; rift; faults; volcanoes; lakes; seas
