How does a volcano erupt

Geography
1 answer:
Nastasia [14]3 years ago
7 0
When it's beneath the surface, the molten rock is called magma. When it reaches the surface, it erupts as lava, ash and volcanic rocks. With each eruption, rocks, lava and ash build up around the volcanic vent. The nature of the eruption depends on the viscosity of the magma.

In order to keep up with the tidal force of the moon, the tidal bulge waveform moves across earth's oceans at a speed of about 1
Kryger [21]

In order to keep up with the tidal force of the moon, the tidal bulge waveform moves across earth's oceans at a speed of about 1,600 KM per hour.

The tidal bulge waveform is the distortion of water and Earth that we call a tidal bulge is a result of deformation of earth and water materials at different places on Earth and response to the combined gravitational effect of Moon and sun. It is  two ocean bulges created on opposite sides of Earth due to the moon's gravitational pull and the ocean's resistance to the pull.

High and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides.

svetlana [45]

Answer:

1. Alexander Oparin's and J. B. S. Haldane's

2. Methane (CH4)

3. Simulate

4. Sparkling device

5. Lightning storm

6. brown broth rich in amino acids

7. Reducing

8. spontaneous organic compound

9. Amino acids.

Explanation:

Miller and Urey performed experiments to support the "Alexander Oparin's and J. B. S. Haldane's" hypothesis. In their experiment, they combined "Methane (CH4)," ammonia, hydrogen gas, and water in a closed system and "Simulate" it to mimic conditions on early Earth. After stimulating the system with a "Sparkling device" to mimic "Lightning Storm, " they discovered that "brown broth rich in amino acids" was produced. This suggests that early Earth had a "Reducing" atmosphere, leading to redox reactions that catalyzed the "spontaneous organic compound" synthesis of organic monomers such as "Amino acids."
