What are the similarities between convergent and divergent boundaries?

The similarities are that a boundary of any kind marks the line between two tectonic plates. Similarities between divergent and convergent boundaries include magma or lava flows, formation of new topographic features and re-shaping of landmasses.

What are three types of convergent boundaries answers?

Three types of convergent boundaries are recognized: continent‐continent, ocean‐continent, and ocean‐ocean.

  • Continent‐continent convergence results when two continents collide.
  • Ocean‐continent convergence occurs when oceanic crust is subducted under continental crust.

Why are transform faults harder to find than divergent and convergent boundaries?

Transform faults are harder to find because they are not single straight lines of movement, it is zigzagged. This term denotes the sliding of two tectonic plates past one another where horizontal motion dominates.

Which fault goes with transform boundaries?

San Andreas Fault

What type of volcanoes form at transform boundaries?

The San Andreas Fault is a transform boundary. Subduction of the Juan de Fuca plate beneath the North American plate creates the Cascade volcanoes. Subduction of the Pacific plate beneath the North American plate in the north creates the Aleutian Islands volcanoes.

Why do volcanoes happen at plate boundaries?

At diverging plate boundaries, earthquakes occur as the plates pull away from each other. Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates. This process, called subduction, takes place because one plate is denser than the other.

Do conservative plate boundaries cause volcanoes?

The earthquakes at a conservative plate boundary can be very destructive as they occur close to the Earth’s surface. There are no volcanoes at a conservative plate margin.

What caused the Eyjafjallajokull volcano to erupt in 2010?

The eruptions of Iceland’s volcano Eyjafjallajökull in 2010 were apparently triggered by a chain reaction of expanding magma chambers that descended into the Earth, a group of researchers now says.

Why was the Eyjafjallajokull eruption so bad?

Farmers near the volcano were warned not to let their livestock drink from contaminated streams and water sources, as high concentrations of fluoride from the ash mixed with river water can have deadly effects, particularly in sheep.

Did Eyjafjallajokull kill anyone?

Health effects No human fatalities were reported from the 2010 eruption of Eyjafjallajökull. The people who lived near the volcano had high levels of irritation symptoms, though their lung function was not lower than expected.

What did Eyjafjallajokull destroy?

Homes and roads were damaged and services disrupted, crops were destroyed by ash and roads washed away. The ash cloud brought European airspace to a standstill during the latter half of April 2010, and cost billions of euros in delays.

Why are Jökulhlaups dangerous?

Subglacial volcanic eruptions are especially hazardous because of the large volumes of meltwater that result, and sometimes because of lahars, rapid and damaging mudflows.

What were the effects of Eyjafjallajokull?

Effects of the eruption within Iceland Areas were flooded because of the glacier melt water which lay above the volcano. Agricultural land was damaged, and farms were hit by heavy ash fall. The ash fall poisoned animals in nearby farms. Some roads were destroyed.

Is Eyjafjallajokull volcano still active?

WILL EYJAFJALLAJÖKULL ERUPT AGAIN? Eyjafjallajokull is an active volcano, meaning it’s still geothermally active and can erupt again in the future. However, this eruption is not likely to occur for a long time.

When did the last eruption of Eyjafjallajökull?
