Answer:

c. their magnetic domains are arranged randomly.      

Explanation:

A material is classified as a magnetic material if its domains are oriented in a single direction or can be oriented in the presence of a magnetic field. Example: iron, nickel, cobalt and materials made of their combination.

In non-magnetic materials, domains are randomly arranged. For example wood, silicon etc.

Due to heat or hammering, a magnet can lose magnetic properties as the orientation of domains becomes random.

What are sunspots? Pls help
liq [111]

Answer:

Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere.

Explanation:

The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them.

Sunspots can be very large, up to 50,000 kilometers in diameter. They are caused by interactions with the Sun's magnetic field which are not fully understood. But a sunspot is somewhat like the cap on a soda bottle: shake it up, and you can generate a big eruption. Sunspots occur over regions of intense magnetic activity, and when that energy is released, solar flares and big storms called coronal mass ejections erupt from sunspots.

What are three kinds of volcanoes? What makes them different?
sashaice [31]

Answer:

Composite, shield, cinder cones, and supervolcanoes are the main types of volcanoes.

Composite volcanoes are tall, steep cones that produce explosive eruptions.

Shield volcanoes form very large, gently sloped mounds from effusive eruptions.

Volcanoes have several shapes, which are controlled by the composition of the magma and the nature of its eruption. If a volcano produces very fluid lava (low in the compound SiO2, or silica), the magma flows a long distance before it cools, making a flat, shield-shaped volcano.
