How long does it take sun to disappear once bottom edge meets horizon at sunset?
It typically takes about 2 to 5 minutes for the Sun to fully disappear below the horizon once its bottom edge touches the horizon during sunset. This can vary depending on atmospheric conditions and your location.
Which layer of soil is made up of only partly weathered rock?
The layer of soil that is made up of only partly weathered rock is called the C horizon, also known as the parent material layer. This layer is located below the B horizon and consists of partially weathered rock fragments that are not yet fully decomposed into soil.
Does agar need to fully solidify to grow bacteria?
Yes, agar needs to be fully solidified before bacterial growth can be observed. Semi-solid agar may not provide enough support for bacterial colonies to grow and be visible.
Why the period of twilight and dawn increases Pole wards?
The period of twilight and dawn increases polewards due to the angle of the Sun's rays hitting the Earth. Near the poles, the Sun's rays are more oblique, which means they spread out more horizontally. This leads to a longer period of diffused light during twilight and dawn, as the Sun's rays take longer to fully disappear below the horizon.
What happens to dark matter at the point of the event horizon?
Dark matter at the event horizon is expected to behave similarly to normal matter. It will be influenced by the extreme gravitational pull and will likely contribute to the mass of the black hole. The specifics of its behavior within the event horizon are still not fully understood.
