space
who was the first person on the moon
Neil Armstrong
What causes earthquakes and volcanoes?
Earthquakes and volcanoes are primarily caused by the movement of tectonic plates.
how does light travel
in waves
in which direction does sound travel
in all directions
what is force
Force is a push or a pull that can cause a change in an object's motion.
how many stars are in our solar system
1
why do so different colors in the rainbow look brighter then other colors
What is reflection?
Reflection is the bouncing back of light when it strikes a surface.
how are echoes created
Echoes are produced when sound waves bounce off a hard surface and return to the listener.
what is motion
Motion is the change in position of an object over time.
how many dwarf planets are in our solar system
5
What are the three types of rocks, and how are they formed?
The three types of rocks are igneous, sedimentary, and metamorphic
What is refraction?
Refraction is the bending of light as it passes from one medium to another
Why do solids transmit sound fastest
In solids, the particles are closely packed and tightly bonded, allowing for efficient transfer of vibrations.
how many laws of motion does Isaac Newton have
3
how do you consider a planet a planet
it has to have a clear neighborhood which means its not in a astroid belt
how do rainbows form
Rainbows form when sunlight interacts with water droplets in the atmosphere. Specifically, sunlight is refracted (bent) and reflected (bounced back) by the water droplets, separating the white light into its component colors and creating a rainbow
How do we see colors?
We see colors because objects reflect certain wavelengths of light and absorb others.
Why can't sound travel through a vacuum
A vacuum is empty space, meaning there are no particles to vibrate. Without particles to carry the sound wave, it cannot propagate,
what is newtons first law of motion
Newton's first law is inertia. that's law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force
what are constellations
constellations are patterns of stars that appear to form shapes in the night sky
What is the difference between weathering and erosion?
Weathering is the breakdown of rocks and minerals at the Earth's surface through physical and chemical processes. Erosion is the transportation of weathered materials by agents like water, wind, or ice.
how do you create light with a prism
To create light with a prism, you need a source of white light and a prism. White light, like sunlight, is actually a mixture of all the colors of the visible spectrum
what is sound waves
Sound waves are a type of mechanical wave that transmits energy through a medium (like air, water, or solids) by causing vibrations
How do you calculate average speed
Average speed is calculated by dividing the total distance traveled by the total time taken: Average speed = Total distance / Total time.
