This is gonna sound stupid but what is lava extrusion again?

Sometimes magma can force itself through a crack or fault in the rock at the Earth's surface. It pours out over the Earth's surface in a volcanic eruption. This process is called extrusion. The rocks that form from extruded magma are called extrusive igneous rocks.

the answer to you question is   jet streams

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)
