Igneous rocks.
2
Objective.
3
To learn about igneous rocks, their types and formation.
4
The Earth's crust is made up of different types of rocks.
5
The rocks which make up the maximum volume of the Earth's crust are called igneous rocks.
6
The word igneous has been derived from the Latin word ignis, which means fire.
7
These rocks are associated with volcanic eruptions.
8
Let's study more about igneous rocks and how they are formed.
9
The liquid rock matter that we see coming out from volcanoes is called magma.
10
It is a hot liquid made of melted minerals.
11
When this magma reaches the earth's surface,
12
it is known as lava.
13
The cooling and the solidification of lava at the Earth's surface result in the formation of extrusive igneous rocks,
14
which are also known as volcanic rocks.
15
Due to rapid cooling, their crystals are fine-grained.
16
However, some of the magma can't come out and settles inside the surface.
17
The magma cools slowly beneath the Earth's surface as it is completely surrounded by the soil and rock present there.
18
The cooling
19
and the solidification of magma at a depth within the Earth's
20
crust result in the formation of rocks having large crystals known as intrusive igneous rocks.
21
So we have learned that igneous rocks are of two types,
22
extrusive igneous rocks and intrusive igneous rocks.
23
It is interesting to know that igneous rocks were the first to be formed and are also known as primary rocks.
24
Pumice and obsidian are extrusive igneous rocks.
25
Pumice is used in making lightweight concrete.
26
And obsidian is used in ornaments.
27
Granite and diorite are intrusive igneous rocks.
28
Both are used as building material.
29
To summarise, Igneous rocks are of two types,
30
extrusive igneous rocks and intrusive igneous rocks.
31
The cooling and the solidification of lava at the Earth's surface result in the formation of extrusive igneous rocks.
32
They are also known as volcanic rocks.
33
The cooling and the solidification of magma at a depth within the Earth's crust result in the formation of intrusive igneous rocks.

常见的发音陷阱
在视频中有一些可能会给学习者带来发音困难的词汇，以下是几个常见的发音陷阱：
- “igneous” - 该词的发音可能对初学者较为复杂，需特别注意每个音节的发音。
- “magma” - 在快语速时，容易导致发音不清晰，反复练习有助于提高准确度。
- “extrusive” - 该词的音节较多，容易发错。多次跟读有助于掌握正确的发音模式。
掌握这些发音特征，能够让你的英语发音更加标准，进一步促进英语口语练习的效果。通过提高自身的发音技能，你不仅能在日常交流中更加自如，还能在专业领域中增加表达的准确性和自信心。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
