Yes, the crust is thinnest under high mountains.
False. The crust is actually thinnest under oceans, not high mountains. Mountain ranges are typically where the crust is the thickest due to the intense tectonic activity that creates them.
False. The crust is actually thinnest under ocean basins due to the presence of dense oceanic crust. Under high mountains, the crust tends to be thicker due to the compression and folding of rock layers.
The mountain tops are the high part of the Earth's crust.

Thickest. The underside of a continental plate approximates in bulk to its upper surface, excluding the sedimentary cover and its landforms. One interesting near-exception is that of the Caucasus. It's wrong to refer to papers without citing them, and I hate doing it, but I have read one that suggests from seismology, that the Caucasus are lower then they "should" be thanks to a large chunk of subducted ocean-crust stuck to their undersides and thus weighing the continental-crust down in that area.
Sure.Every island is basically a mountain that's high enough to break the surface.Yes, Volcanoes.
Eclogite is typically found in high-pressure and high-temperature environments, such as subduction zones where oceanic crust is being pushed beneath continental crust. It is commonly found in mountain belts, particularly in regions with complex tectonic histories like the Alps, Himalayas, and Andes.
The crust under continents is composed mainly of granite and granodiorite, which are igneous rocks. These rocks are less dense and thicker compared to the oceanic crust, providing the continents with their high elevation and stability. Additionally, the continental crust also contains sedimentary and metamorphic rocks, formed through the processes of erosion and tectonic activity.

A high mountain made of lead is impossible on Earth because lead is a heavy metal that is not naturally found in large concentrations in mountainous formations. Additionally, lead is not a primary component of Earth's crust, which is composed mainly of lighter materials like silicon and oxygen. The weight and density of lead would also make constructing and supporting a mountain made of lead impractical.
Diamonds typically take millions to billions of years to form in the Earth's crust under high pressure and temperature conditions.
Trenches and mountain ranges are both formed by tectonic plate movements. Trenches are formed where one tectonic plate is subducted under another, creating deep oceanic trenches. Mountain ranges are formed when tectonic plates collide, pushing up the Earth's crust to form high elevations.
