A upwarped mountain is a mountain consisting of a broad area of the Earth's crust that has moved gently upward without much apparent deformation, and usually containing sedimentary, igneous, and metamorphic rocks
Any mountian that forms over a hot spot is volcanic. The molten rock rises to the earth's surface in a mantle and forms a volcano
As we know, low air pressure often causes it to rain. When moist winds blow over mountains, the air on the other side is thinned out - the pressure is lowered. This causes rain to fall.
Moist air masses usually form over warm tropical oceans.

sometimes warm, moist air is forced upward when passing over high landforms such as mountains, causing precipitation. this affect is called rain shadow, this is common on seacoasts where moist, ocean winds blow toward coastal mountains.

A maritime tropical or warm, moist air mass.
The Difference of CT and MTContinental Tropicalair mass is more hot and dry, and forms over water. Maritime Tropical is more warm and moist and forms over land.
The Maya Mountains are in Belize and Guatemala. They are a large uplifted block of intrusive Paleozoic granite and sediment. The granite comes from liquid rock under the Earth's surface that was pushed up over millions of years and cooled into granite, a process that occurred several hundred million years ago.
Mountains act as a focus for rising air currents that contain some humidity. As the air rises it forms clouds over the mountains and rain occurs there before it moves over the desert.

Uplifted is a term that is applied to a mass of rock that is pushed up by geologic forces. Uplifting can occur in a few different ways and can be accompanied by faulting. A fault block is a mass of rock that is separated from the surrounding rock by faults. Depending on the setting a fault block may be uplifted (move up), be downthrust (move down), or may move sideways with out vertical movement.
This is one way that mountains form.
Dry air masses come off the Rocky Mountains as a result of the rain shadow effect. When this plows into warm, moist air from the Gulf of Mexico it creates a dry line. The dry air lifts the less dense moist air, which triggers powerful thunderstorms. These thunderstorms have the potential to produce tornadoes.
