What are the three main types of nebulae?

• Galactic Nebulae

• Emission Nebulae, Reflection Nebulae, Dark Nebulae

• Planetary Nebulae

• Supernova Remnants

How do emission nebulae differ from reflection nebulae?

• Emission nebulae are found only in galaxies; reflection nebulae are found only in star clusters.

• Emission nebulae are always blue; reflection nebulae are always red.

• Emission nebulae are cooler than reflection nebulae.

• Emission nebulae emit their own light; reflection nebulae reflect light from stars.

What is a planetary nebula and how is it formed?

• A planetary nebula is a shell of gas and dust ejected by a dying star, formed after the star exhausts its nuclear fuel and sheds its outer layers.

• A planetary nebula is a black hole that absorbs surrounding matter.

• A planetary nebula is a solid object that orbits a star.

• A planetary nebula is a type of galaxy formed from star collisions.

Describe the process of tectonic plate formation.

• Tectonic plates are formed through mantle convection, leading to divergent boundaries and subduction zones.

• Tectonic plates are created through the cooling of ocean water.

• Tectonic plates are formed by volcanic eruptions alone.

• Tectonic plates are formed by the collision of asteroids in space.

What are the main types of plate boundaries?

• Erosion, Sedimentation, Metamorphism

• Divergent, Convergent, Transform

• Subduction, Compression, Expansion

• Lateral, Vertical, Horizontal

How do divergent boundaries affect tectonic plates?

• Divergent boundaries lead to the destruction of crust and earthquakes.

• Divergent boundaries cause tectonic plates to move apart, creating new crust and leading to geological features like mid-ocean ridges.

• Divergent boundaries have no effect on tectonic plates.

• Divergent boundaries cause tectonic plates to collide, forming mountains.

What happens at convergent plate boundaries?

• Tectonic plates slide past each other without interaction.

• Tectonic plates collide, causing subduction, mountain formation, earthquakes, and volcanic activity.

• Tectonic plates remain stationary, causing no geological activity.

• Tectonic plates move apart, creating new oceanic crust.

Explain the significance of transform boundaries.

• Transform boundaries are primarily responsible for volcanic activity.

• Transform boundaries are only found in oceanic regions.

• They have no impact on earthquake formation.

• Transform boundaries are crucial for understanding seismic activity and the dynamics of Earth's crust.

What are the layers of the Earth?

• Core, Shell, Surface, Subsurface

• Crust, Mantle, Atmosphere, Lithosphere

• Lithosphere, Asthenosphere, Mesosphere, Exosphere

• Crust, Mantle, Outer Core, Inner Core

How do tectonic plates interact with the Earth's layers?

• Tectonic plates interact at their boundaries, causing geological activity.

• Tectonic plates only affect ocean currents and not geological activity.

• Tectonic plates are stationary and do not interact with the Earth's layers.

• Tectonic plates are made of liquid and flow freely within the Earth's mantle.
