Hypothesize where you think the major plate boundaries exist and draw those boundaries on the blank map in Figure 1.6 using three different colors to identify the type of motion for each boundary (example:
red
for divergent boundaries, blue for convergent boundaries
What is a location where divergent boundaries occur?
Perhaps the best known of the divergent boundaries is the
Mid-Atlantic Ridge
. This submerged mountain range, which extends from the Arctic Ocean to beyond the southern tip of Africa, is but one segment of the global mid-ocean ridge system that encircles the Earth.
Where are divergent boundaries located on a map?
The
boundary between the North America Plate and the Eurasian Plate
is an example of a divergent boundary at a mid-ocean ridge. All of the plate boundaries that occur down the center of the Atlantic Ocean are divergent boundaries that follow the crest of the Mid-Atlantic Ridge.
What land formations occur at divergent boundaries?
Most divergent plate boundaries are underwater and form submarine mountain ranges called
oceanic spreading ridges
. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
What are the examples of divergent boundary?
- Mid-Atlantic Ridge.
- Red Sea Rift.
- Baikal Rift Zone.
- East African Rift.
- East Pacific Rise.
- Gakkel Ridge.
- Galapagos Rise.
- Explorer Ridge.
What are the 4 plate boundaries?
There are four main types of plate boundary. These are
constructive, destructive, conservative and collision margins
.
What are the 2 types of divergent boundaries?
At divergent boundaries, sometimes called constructive boundaries, lithospheric plates move away from each other. There are two types of divergent boundaries, categorized by where they occur:
continental rift zones and mid-ocean ridges
.
Which of the following best describes divergent boundaries?
Which of the following best describes what happens at a divergent plate boundary?
The plates separate from each other creating new crust in the process
. … Neither plate is subducted; instead, both are lifted up forming a mountain range.
Which geologic features are associated with divergent boundaries?
Divergent Plate boundaries are associated with
Very long underwater mountain ranges known as ridges
. Between the Ridges is a Rift Valley. This is where Sea Floor Spreading occurs. There are underwater hydrothermal vents and paleomagetic banding.
What are 3 things that are formed at a divergent boundary?
Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity;
creation of new seafloor and a widening ocean basin
.
What is another name for Transform boundaries?
A transform fault or transform boundary, sometimes called
a strike-slip boundary
, is a fault along a plate boundary where the motion is predominantly horizontal.
Do divergent boundaries cause volcanoes?
Most volcanoes form at the boundaries of Earth’s tectonic plates. … The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.
What is an example of divergent evolution?
Galapagos finches
are an example of divergent evolution. Through time, the species evolved morphologically different traits. A prototype example of divergent evolution is Galapagos finches. … Thus, they become a different species to their ancestors and what was once one species has diverged into two.
What are the non examples of divergent boundaries?
- Ocean.
- Earthquake.
- Landforms.
- Tsunami.
- Fault.
What is form in divergent boundaries?
A divergent plate boundary often forms
a mountain chain known as a ridge
. This feature forms as magma escapes into the space between the spreading tectonic plates.
What are the 7 plate boundaries?
There are seven major plates:
African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American
. The Hawaiian Islands were created by the Pacific Plate, which is the world’s largest plate at 39,768,522 square miles.
