Explanation

Tectonic Plates Movement (Most Common): The Earth's crust is broken into large tectonic plates that constantly shift. 

Volcanic Activities: Movement of magma beneath volcanoes can cause shifts and trigger earthquakes.

Tectonic Dislocation (Faults): This refers to the actual fractures (faults) in the crust where plates slide past each other, which is the direct mechanism for most plate-related earthquakes.

Other Causes: Human activities (mining, large reservoirs) and even large collapses of rock can also cause minor seismic events. 

Explanation

• The planet that moves around the Sun at the largest speed is Mercury
• ***
• Mercury is the fastest planet, which speeds around the sun at 47.87 km/s.
• In miles per hour, this equates to a whopping 107,082 miles per hour.

Explanation

Earth is the densest planet in the solar system, with an average density of 5.52 g/cm³.

Its high density is due to a large iron-nickel core and rocky mantle.

Saturn is the least densest planet in the solar system.

Explanation

Explanation

The photosphere is the lowest layer of the Sun's atmosphere.

It is the specific part that is visible to the human eye from Earth.

The term literally means "sphere of light," as most of the Sun's visible light is radiated from this layer.

It is important to note that the Sun has no solid surface.

As it is a giant ball of gas (plasma).

So the photosphere serves as its effective visible boundary. 

Explanation

Studies show that it takes an average of 8 minutes and 20 seconds for sunlight to move from the sun to the earth.

Sunlight moves at the speed of light.

You can see that the distance of the sun from the earth = 149.6 x 106 km.

Photons emitted from the surface of the sun need to traverse the vacuum of the universe to reach our eyes.

Explanation

Accretion is the process where a black hole pulls in surrounding gas, dust, and matter due to its strong gravitational pull.

This material forms an accretion disk around the black hole before being absorbed.

Explanation

Explanation:

1. Venus is the closest planet to Earth.

2. Earth is the second planet.

3. Mars comes after Earth in the order of planets from the Sun.

4. Jupiter is the fifth planet from the Sun and the largest planet in our solar system.

Explanation

Ganymede is the largest and most massive moon of Jupiter and in the entire Solar System,

With a diameter of about 5,270 kilometers (3,270 mi).

It is even larger than the planet Mercury.

Explanation

• Mars is referred to as the Red Planet.
• It has rivers, streams, lakes, and oceans.
• It has the largest volcano Olympus Mons.
• It has two moons; Deimos and Phobos.
