The Proclamation Line of 1763 was a British-produced boundary marked in the Appalachian Mountains at the Eastern Continental Divide. Decreed on October 7, 1763, the Proclamation Line prohibited Anglo-American colonists from settling on lands acquired from the French following the French and Indian War.
Explanation
Heath and pressure manage to move the material between the bottom and top part of the mantle, causing currents, and affecting the surface of Earth.
Explanation:
The heat and the pressure are crucial for the cycling of matter on our planet. This process happens in the mantle layer. The lower part of the mantle is hotter because of the higher influence by the core, while the upper part is not as hot (though very hot for surface standards). This causes the material in the upper part to be more solid and denser, which in turn causes it to sink toward the bottom. As this material sinks the hotter and less dense one from the bottom is pushed upward. This creates the convection currents.
As the material from the bottom moves upward it comes in contact with the lithosphere. It puts a lot of pressure on it and supported by the heat manages to crack it, which created the tectonic plates. Because of the constant pressure the tectonic plates are pushed and moved on the surface of Earth. On some places (subduction zones) the crust from the surface sinks into the mantle, while from the mantle we have rise of magma toward the surface, so the material is constantly circling and being recycled.
<span>SMCRA stands for the Surface Mining Control and Reclamation Act of 1977 (SMCRA). The SMCRA is a federal law that controls how much the coal mining companies can pollute the environment. The Surface Mining Control and Reclamation Act regulates how old mines are reclaimed in addition to controlling how new coal mines are opened and how they operate.</span>

Explanation:
Answer:
Sidereal Time is the shortest time of earth and Synodic time is longest time of the sun.
Explanation:
<u>shortest to the longest time.
</u>
- Sidereal day and one rotation of the earth on its axis.
- Sidereal month and one full orbit around the earth.
- Synodic month and one full cycle of the moon.
- Solar day i.e Earth rotation on its axis so that the sun appears same on the sky.
As sideral refers to the events that occur on the same day with 23 hours 56 minutes 4.091 sec, and synodic day refers to the 24 hours and 2.5 ms aligned to astronomical bodies. Each synodic day the gradual motion is one degree eastwards. (360 degrees per year.)
The solar day is just one complete solar day. Time is calculated based on sun positioning of the solar clock i.e 24 hr format and the mean solar time is 12 hours.
Solar time does include the moon phases as this phenomenon is limited to the sidereal rotation of the earth on its axis. Aphelion and Perihelion are caused by the earth's rotational effects towards the sun being exposed at the time of day.
