No it is not polite to throw away your trash facing upwards because then the people behind you have to look at the food you trough away. And its better for kids because then they can hide all the food they didn't eat and still be polite!
When one tectonic plate presses into another it can either force it upwards or downwards. If it is upwards, then mountains are formed as the plate pushes up the surface of the earth above it.
Above the skid plate, facing diagonally upwards
The Rocky Mountains were formed by the collision of tectonic plates, the North American plate and the Pacific plate. When they collided, rock on each side was forced upwards or downwards. So rocks came up out of the ground on the west side of the North American Plate.
It is not polite to finish your plate in Italy. To finish one's plate in Italy means they were bored or overeating.
The dinner knife, or 'service knife,' in a semi-formal, or formal setting would be for the knife to be at the right of the dinner plate, with the blade facing the plate. If there is a butter plate and butter knife or 'spreader,' that knife should be on the butter plate to the left of the dinner plate, just above the cutlery on the left. The butter knife should be place with the handle facing to the right and the blade facing downwards. If there is an additional knife, such as a fish knife, etc., that knife should be to the right of the dinner knife, with the blade facing towards the dinner knife.
Either both sides of the plates are thrust upwards to form mountains. Or one side is thrust downwards beneath the other, known as subduction.
it moves upwards into the eurasian plate to form Himalayas
A constructive plate boundary, as it pushes land upwards (which formed the mountains)
When there is a collision between a continental and oceanic plate, the oceanic plate plunges downwards into the asthenosphere while the continental plates rises upwards/thrusted above, this is due to the fact that the oceanic crust is denser so it sinks, while the lighter and more bouyant continental crust is displaced upwards. This process is referred to as "Subduction". The area where it takes place is called the "Subduction Zone". This phenomenon results into Geological Activities, Processes, Formations and Features/Landforms such as Trenches, Volcanism (Volcanoes/Volcanic Eruption), Island Arcs, Metamorphism, and Mineralization.
In the case of the Indian Plate colliding with the Asian Plate, the Indian Plate pushed under the harder Asian Plate, and the Himalayan mountain range was thrust upwards.
The Himalayan Mountain Range was thrust upwards when the Indian Plate crashed into the European Plate.
The crashing of the India plate into the Asia plate resulted in the thrusting up of the Himalayas. Another possibility is subduction, where one plate is pushed downwards into the mantle.
