Cosmic and Earth Science

How are stars formed?

• Stars are formed from clouds of gas and dust in space, known as nebulae.

• Stars are formed from the collision of asteroids and comets.

• Stars are created by the gravitational pull of black holes.

• Stars are the remnants of exploded supernovas.

What are the different types of nebulae?

• Solar nebulae, Lunar nebulae, Martian nebulae, Venusian nebulae

• There are four main types of nebulae: emission nebulae, reflection nebulae, dark nebulae, and planetary nebulae.

• Supernova nebulae, Black hole nebulae, Quasar nebulae, Pulsar nebulae

• Star nebulae, Galaxy nebulae, Comet nebulae, Asteroid nebulae

What are the three main types of galaxies?

• Round, square, and triangle

• Big, medium, and small

• Spiral, elliptical, and irregular

• Red, blue, and green

What are tectonic plates and how do they move?

• Tectonic plates are large pieces of the Earth's lithosphere that move due to the heat from the Earth's core and the forces of gravity.

• Tectonic plates are made of ice and move due to the wind

• Tectonic plates are controlled by aliens and move according to their instructions

• Tectonic plates are small pieces of the Earth's crust that don't move

What is the primary cause of earthquakes?

• Volcanic eruptions

• Meteorite impacts

• Movement of tectonic plates

• Global warming

How does volcanic activity contribute to the formation of new land?

• By accumulating lava and volcanic ash, which solidify and build up over time.

• By releasing gases that solidify and create new land

• By causing earthquakes that push up new land formations

• By attracting water and forming new landmasses

What is the process of star formation called?

• celestial birth

• galactic creation

• cosmic genesis

• stellar formation

Name one type of nebula and describe its characteristics.

• Reflection nebula

• Planetary nebula

• Black hole

• Emission nebula

What are the differences between elliptical, spiral, and irregular galaxies?

• They are all the same in shape and structure

• The shapes and structures of elliptical, spiral, and irregular galaxies are different.

• The colors of the galaxies are the only difference

• The size of the galaxies is the only difference

Explain the concept of plate tectonics and its impact on Earth's surface.

• Plate tectonics is the theory that Earth's surface is flat and does not move, and its impact includes causing the formation of valleys and plains.

• Plate tectonics is the theory that Earth's outer shell is divided into several plates that rotate around the core, and its impact includes causing the formation of deserts and oceans.

• Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the atmosphere, and its impact includes causing the formation of clouds and rain.

• Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, and its impact includes causing earthquakes, volcanic activity, and the formation of mountains.
