A deep narrow valley with steep sides formed as a result of rapid down-cutting by the stream is termed as A) Gorge B) Meander C) Lagoon D) Lake
Answers
Answer:
Gorge
Explanation:
A gorge, by definition, is a narrow valley between hills or mountains, often with steep rocky walls and a waterway such as a river or stream running through it. The running water is often the cause of the steep sides and depth.

The Big Bang Theory is a widely accepted scientific explanation for the origin of the universe.
↪ According to this theory, the universe began as a singularity—an infinitely dense and hot point—in an event known as the Big Bang. Around 13.8 billion years ago, this singularity began to expand rapidly, resulting in the formation of all matter, energy, space, and time.
As the universe expanded and cooled, subatomic particles like protons, neutrons, and electrons began to form. These particles eventually combined to create atoms, which in turn formed molecules. Over billions of years, gravity led to the clumping of matter, giving rise to galaxies, stars, and planetary systems.
One of the key pieces of evidence supporting the Big Bang Theory is the observed cosmic microwave background radiation—a faint glow of radiation that fills the universe. This radiation is a remnant of the initial moments after the Big Bang and provides valuable insights into the universe's early conditions.
Additionally, the abundance of light elements like hydrogen and helium in the universe also aligns with the predictions of the Big Bang Theory. As the universe expanded and cooled, the conditions became suitable for the formation of these elements.
While the Big Bang Theory provides a comprehensive explanation for the universe's origin and early evolution, there are still questions that remain unanswered, such as the nature of dark matter and dark energy, which together make up most of the universe's content.
In summary, the Big Bang Theory posits that the universe began as a singularity and has been expanding and evolving ever since. This theory has garnered substantial evidence and support from observations and experiments, offering a compelling narrative for the origin and development of our universe.

Answer:
The orbital angular momentum of the Earth is equal to the product of the mass of the Earth (6.0x 10^24 kg) and its orbital velocity (29.7 km/s) multiplied by its distance from the Sun (1.5x 10^8 km), which results in a magnitude of 3.6x 10^40 kg m^2/s.
The spinning angular momentum of the Earth is equal to the product of its mass (6.0x 10^24 kg) and its angular velocity (7.3x 10^-5 radians/s) multiplied by the square of its radius (6.4x 10^6 m), which results in a magnitude of 3.8x 10^37 kg m^2/s.
Final answer:
a) The magnitude of Earth's orbital angular momentum with respect to the Sun is [ Select ] kg m^2/s. b) The magnitude of its spinning angular momentum is [Select ] kg m^2/s.
Explanation:
To calculate the magnitude of Earth's orbital angular momentum with respect to the Sun, we need to use the formula:
Angular Momentum = Moment of Inertia * Angular Velocity
For Earth's orbital angular momentum, the moment of inertia can be calculated using the formula for a sphere:
Moment of Inertia = (2/5) * mass * radius^2
Substituting the given values:
Moment of Inertia = (2/5) * 6.0 x 10^24 kg * (6.4 x 10^6 m)^2
Next, we need to calculate the angular velocity. The time taken for Earth to complete one revolution around the Sun is known as the orbital period. The orbital period of Earth is approximately 365.25 days or 31,557,600 seconds.
Angular Velocity = 2π / Orbital Period
Substituting the values:
Angular Velocity = 2π / 31,557,600 s
Now, we can calculate the orbital angular momentum:
Orbital Angular Momentum = Moment of Inertia * Angular Velocity
For the spinning angular momentum, we can use the same formula:
Spinning Angular Momentum = Moment of Inertia * Angular Velocity
However, the moment of inertia for spinning angular momentum is different. It depends on the mass distribution of Earth and its axis of rotation. Since Earth is considered a sphere, the moment of inertia for spinning angular momentum can be calculated using the formula mentioned earlier.
Substituting the given values:
Moment of Inertia = (2/5) * 6.0 x 10^24 kg * (6.4 x 10^6 m)^2
Finally, we can calculate the spinning angular momentum:
Spinning Angular Momentum = Moment of Inertia * Angular Velocity
