Explanation

• waves transfer by energy
• ****
• 'Wave' is a common term for a number of different ways in which energy is transferred: In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields.
• Waves transfer energy but not mass
• A wave transports its energy without transporting matter.

Explanation

The solar system is a system constrained by the gravity of the sun and the objects that orbit it. The solar system was formed 4.6 billion years ago by the gravitational collapse of a huge interstellar molecule cloud.

Explanation

The age of Earth is estimated to be 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%)

Earth is the third planet from the Sun 

This age has been obtained  from the isotopic of many meteorites 

Explanation

• Sunspots are darkish, planet-sized regions that seem on the "floor" of the sun. Sunspots are "darkish" because they're cooler than their environment.
• A big sunspot would possibly have a critical temperature of 4,000 ok (about three,seven hundred° C or 6,seven hundred° F), tons lower than the five,800 ok (about five,500° C or 10,000° F) temperature of the adjacent photosphere.
• Sunspots are most effective darkish in evaluation to the bright face of the sun. If you may reduce a median sunspot out of the sun and place it someplace else within the night time sky, it might be about as shiny as a complete moon.
• Sunspots have a lighter outer segment referred to as the penumbra, and a darker central area named the umbra.
  

Explanation

 Asteroids are rocky worlds revolving around the sun that are too small to be called planets.

They are also known as planetoids or minor planets.

Explanation

C

A total solar eclipse occurs when the Moon is exactly positioned between the Sun and the Earth and the Earth passes through the Moon's shadow. Solar eclipses can only happen during the day and at the time of a new Moon. Total solar eclipses last for only a few minutes.

while on the other hand 

During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. There are two kinds of lunar eclipses: A total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth.

Explanation

The winter solstice, also called the hibernal solstice, occurs when either of Earth's poles reaches its maximum tilt away from the Sun.

This happens twice yearly, once in each hemisphere. 

Also called: Midwinter; the Shortest Day; the Longest Night

Explanation

At this position, neither of the poles is tilted towards the sun i.e shines vertically overhead at noon on the Equator.
