What are the three main types of tectonic plate boundaries?

• Subduction, Compression, Expansion

• Divergent, Convergent, Transform

• Lateral, Vertical, Radial

• Static, Dynamic, Rotational

How do divergent boundaries affect the Earth's surface?

• Divergent boundaries cause the Earth's crust to sink.

• Divergent boundaries lead to the formation of mountain ranges.

• Divergent boundaries have no impact on volcanic activity.

• Divergent boundaries create new crust, form mid-ocean ridges, and can lead to volcanic activity and earthquakes.

What is the primary characteristic of convergent boundaries?

• The movement of tectonic plates away from each other.

• The movement of tectonic plates towards each other.

• The sliding of tectonic plates past each other.

• The formation of new oceanic crust.

Describe the process that occurs at transform boundaries.

• Transform boundaries are locations where tectonic plates sink into the mantle, causing volcanic activity.

• Transform boundaries are where tectonic plates collide, forming mountains.

• Transform boundaries are locations where tectonic plates slide past each other, causing earthquakes.

• Transform boundaries are areas where tectonic plates move away from each other, creating new crust.

What role do tectonic plates play in the formation of mountains?

• Tectonic plates create mountains through volcanic activity alone.

• Mountains are formed by the erosion of tectonic plates over time.

• Tectonic plates have no impact on mountain formation.

• Tectonic plates cause mountains to form primarily through the process of convergence and collision, leading to the uplift of the Earth's crust.

What is a nebula and how does it form?

• A nebula is a solid object in space made of metal.

• A nebula is a cloud of gas and dust in space that forms from star remnants or gas collapse.

• A nebula is a planet that orbits a star.

• A nebula is a type of star that emits light.

Explain the significance of gravity in the formation of nebulae.

• Nebulae form solely from nuclear fusion processes.

• Gravity has no effect on nebulae formation.

• Gravity is significant in nebulae formation as it causes gas and dust to clump together, leading to increased density and potential star formation.

• Gravity only influences planets, not nebulae.

What are the stages of a star's life cycle?

• Nebula, Protostar, Main Sequence, Red Giant/Supergiant, White Dwarf/Neutron Star/Black Hole

• Protostar, Red Giant, Brown Dwarf

• Black Hole, Red Supergiant, Main Sequence

• Gas Giant, Red Dwarf, Blue Supergiant

How does a star's mass affect its life cycle?

• All stars have the same lifespan regardless of mass.

• A star's mass has no impact on its life cycle.

• More massive stars live longer than less massive stars.

• A star's mass significantly affects its life cycle, with more massive stars having shorter lifespans and different end states compared to less massive stars.

What happens during the main sequence phase of a star?

• A star fuses hydrogen into helium in its core, producing energy.

• A star cools down and stops shining.

• A star explodes into a supernova.

• A star absorbs helium and converts it into hydrogen.
