Precipitation contributes to the formation of groundwater by:

seeping into the soil and replenishing underground water reserves

evaporating immediately after reaching the ground

remaining on the surface as runoff only

being absorbed only by plants and not entering the ground

How many active volcanoes are there on Earth today?

There are over 600 active volcanoes on Earth today.

There are over 100 active volcanoes on Earth today.

There are over 60 active volcanoes on Earth today.

There are over 6,000 active volcanoes on Earth today.

A volcano is essentially a rupture in the Earth's crust—the Earth's rocky outermost layer that lies on top of its hotter inner layers.

A volcano is a large body of water found in deserts.

A volcano is a type of plant that grows in cold regions.

A volcano is a man-made structure used for storing food.

What do the Earth's crust and the upper mantle form?

The Earth's crust and the upper mantle form the lithosphere.

The Earth's crust and the upper mantle form the asthenosphere.

The Earth's crust and the upper mantle form the core.

The Earth's crust and the upper mantle form the biosphere.

What are tectonic plates?

Tectonic plates are slabs that make up the lithosphere and fit together like puzzle pieces to make up the surface of the Earth.

Tectonic plates are large bodies of water that cover the Earth's surface.

Tectonic plates are layers of the atmosphere above the Earth.

Tectonic plates are types of rocks found only in volcanoes.

Where are most volcanoes found ?

Most volcanoes are found along tectonic plate margins, either at a destructive or constructive plate margin.

Most volcanoes are found in deserts far from any water sources.

Most volcanoes are found in the middle of large continents, away from any plate boundaries.

Most volcanoes are found only at the North and South Poles.

At a destructive or convergent plate margin, what happens when an oceanic tectonic plate and a continental plate move towards each other?

The denser oceanic plate sinks under the continental plate, melting down into the Earth's mantle.

The continental plate sinks under the oceanic plate, forming a new ocean ridge.

Both plates move upwards, creating a mountain range without any subduction.

The plates slide past each other without any significant geological activity.
