Sills
The formations that are sandwiched between layers of existing rock formations called sills. Another formation between layers is called laccoliths.
A geologist studies rock formations. A seismologist studies earthquakes.
The vast majority of weather processes occur in the troposphere, which is below the stratosphere. The boundary between them is called the tropopause. Some cloud formations occur in the stratosphere, but these are rare, and any weather that occurs is not well understood.
It is where a layer of underground water is sandwiched between layers of sediment and rock.
it is a sloping layer of permeable rock sandwiched between two layers of impermeable rock and exposed at the surface.

No. Intrusions are used to describe the process and resulting structure where igneous rocks force there way into or between pre-existing rock formations.
Plutons can be classified according to size and shape. A dyke is a sheet pluton that cuts across existing rock formations, a sill has a tabular form that intrudes between two existing rock formations, a batholith is a large irregular shaped emplacement. Plutons can also be classified based on the type of rock composition. Many plutons are formed from either granite, granodiorite, quartz diorite, or monzonite.
Melted cheese!

A peltast was a light infantryman, unarmoured, equipped with crescent shaped shield and javelins, used to harrass armoured infantry formations and archers, and as well fill the gap between armoured infantry formations and their flanking cavalry. They were mainly hired from the tribesmen of Thrace.
The most common border-marking geological formations between Portugal and Spain are rivers, not mountains. There is no specific mountain range marking the border.
Seaweeds are living organisms, members of the Algae family. Stalactites (and Stalagmites) are formations of limestone which occur in caves, they are not living organisms.
Sedimentary Siltstone and Sandstone called the Kayenta Formation and in the Glen Canyon geologic layer between Navajo and Wingate Sandstone.
Plate tectonics is the theory used to explain the structure of the Earth's various formations and plate boundaries between the major tectonic plates.
When in a trench a soldier is basically dug into the earth itself. This provides a very stable, protective, and defensible line. These defenses were often bolstered with fortified structures made of concrete and steel. Considering that no-man's land (the areas in between opposing trench lines) was often difficult to cross considering the massive amounts of barbered wire used and the advent of the machine-gun, attacking infantry and cavalry formations (as WWI until later on pre-dated armor) were easy targets for defending infantry formations. The barbed wire slowed formations down and made them also easy targets for artillery.
