Question

1The outermost layer of the earth is called mantle

2 The hot liquid below the earth's surface is called lava.

3 The hot liquid that erupts on earth's surface through a volcano
is called magma

4 Lava is a hot liquid with temperature as high as 100 degrees
Celsius.

5 The hot liquid flowing on earth's surface cools down to form
rivers.

6 Basalt and graphite are examples of metamorphic rocks.

7 A dormant volcano has not erupted in a long time and can never
erupt again

8 Volcanoes are of three types active, dormant and dead.

Answer 1

Answer:

1. The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.
2. Magma is extremely hot liquid and semi-liquid rock located under Earth's surface. When magma flows onto Earth's surface, it is called lava.
3. Lava (magma that has erupted onto the Earth's surface) is visually mesmerizing – as the molten rock flows downhill, lava exposed to the air cools to a deep black color, while the molten rock beneath glows bright orange. Magma is extremely hot liquid and semi-liquid rock located under Earth's surface.
4. Lava is extremely hot. Lava can reach temperatures of about 1,250° Celsius.
5. Most of the lava then runs down the side of the volcano like a hot, glowing river. ... This is called a lava flow. As the lava cools, the flow slows down and thickens, before it stops and eventually turns back into solid rock.
6. Granite, basalt, and andesite are types of igneous rocks. Rocks are considered metamorphic if the "proto-lith" is exposed to enough heat and pressure to change the mineralogy and/or structure and/or chemical composition, without significant melting. ... Shale, halite, and limestone are examples of sedimentary rocks.
7. A dormant volcano is an active volcano that is not erupting, but supposed to erupt again. An extinct volcano has not had an eruption for at least 10,000 years and is not expected to erupt again in a comparable time scale of the future.
8. An active volcano is a volcano that has had at least one eruption during the past 10,000 years. An active volcano might be erupting or dormant. An erupting volcano is an active volcano that is having an eruption... A dormant volcano is an active volcano that is not erupting, but supposed to erupt again.
