CLOUDS ARE

THIN AND

FEATHER- LIKE.

THEY ARE

HIHEST OF ALL

CLOUDS.


Clouds are flat

mountain like


Are dull and gray in

are the weather

elements?


Read a poem “All things bright and beautiful

What can you say about the poem? Where do we usually see the birds, the different flowers and trees

Assignment




Volcano

(Volcanic structure)


A magma chamber is a large

underground pool of molten rock

sitting underneath the Earth’s crust.

This magma is less dense than the

surrounding mantle and so it seeps

up to the surface through cracks and

flaws in the crust. When it reaches

the surface, it results in a volcanic

eruption.Prepared by: Michaella M. Dela Cruz 20

Lava is the rock expelled from a volcano

during an eruption. When it first comes out,

the lava can have a temperature higher than

700 degrees C. It then flows downhill from

the eruption point until it cools and

hardens.


A volcano’s main vent is the point in

the Earth’s crust where hot magma

has reached the surface. The

familiar cone-shaped volcano builds

up as ash, rock and lava ejected

during eruptions fall back to Earth

around the vent.


A volcanic crater is a circular

depression in the ground caused

by volcanic activity. A volcano’s

vents are located at the bottom of

the crater.


OHP


Relate the story of going to a

mountain trek in Taal.


a. Volcano is an opening in the earth’s

surface through which hot gases, ash

and molten rock are ejected.

b. The parts of volcano are the channel

or vent, magma chamber, cone, and

crater.

c. Volcanoes are classified based on the

composition of its cones and their level

of activity.


Describe the following:

Magma Chamber

Lava

Main Vent

Crater
