What is lava? What is an ash cloud? What is magma? What is a crater ? What is a volcano? пожалуйста ответьте на вопросы !срооочноо​ на английском

Answer 1

Ответ:

Lava is molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon. Ash cloud is occur where a violent explosive eruption ejects volcanic ash into the atmosphere. Magma is the molten or semi-molten natural material from which all igneous rocks are formed. Volcano is a rupture in the crust of a planetary-mass object, such as Earth

Answer 2

Sure, I'd be happy to answer your questions!

1. Lava: Lava is molten rock that flows from a volcano during an eruption. It is extremely hot, often reaching temperatures of 700 to 1,200 degrees Celsius (1,292 to 2,192 degrees Fahrenheit). Lava can vary in composition, ranging from basaltic (less viscous) to andesitic or rhyolitic (more viscous), which influences how it flows and behaves.

2. Ash Cloud: An ash cloud is a dense cloud of tiny volcanic ash particles and gases that is released into the atmosphere during a volcanic eruption. These particles can be fine as dust or larger, resembling small rocks. Ash clouds can pose significant hazards to aviation, as they can damage aircraft engines and affect visibility.

3. Magma: Magma is molten rock beneath the Earth's surface. It is the precursor to lava and is formed when rocks in the Earth's mantle melt due to high temperatures and pressure. Magma can vary in composition, and its properties influence the type of volcanic eruption that occurs when it reaches the surface.

4. Crater: A crater is a bowl-shaped depression or cavity that forms at the top of a volcano. It is typically created by volcanic eruptions when material is ejected from the volcano, leaving a void or depression behind. Craters can vary in size and depth and are often a prominent feature of volcanoes.

5. Volcano: A volcano is a geological feature on the Earth's surface that results from the eruption of molten rock (magma), ash, and gases. Volcanoes can vary widely in size, shape, and activity. They can be classified into several types, such as stratovolcanoes (composite volcanoes), shield volcanoes, cinder cone volcanoes, and more, based on their characteristics and eruption patterns.

I hope these explanations help! If you have any more questions or need further clarification, feel free to ask.
