It's chief property is that it is (easily) split into thin sheets.
When slate is heated, it expands due to the thermal energy causing the mineral grains to separate. This expansion can lead to cracks or breakage in the slate. Additionally, heating slate can alter its mineral composition and structure, affecting its physical and chemical properties.
No, slate rock is typically not attracted to a magnet because it is composed mainly of minerals like clay and quartz, which are not magnetic. Magnetic properties in rocks are usually found in those containing iron minerals, such as magnetite.
yes, slate is metamorphic rock
Slate is formed from the metamorphism of shale or mudstone. This process involves intense heat and pressure which causes the shale to recrystallize into a fine-grained, foliated rock with excellent cleavage properties.
If the pressure on slate increases, it can lead to metamorphism, resulting in the transformation of slate into a denser rock known as phyllite or schist, depending on the degree of pressure and temperature. This process alters the mineral composition and texture, causing the rock to develop a more pronounced foliation or layering. Additionally, the physical properties of the slate may change, making it more compact and resilient.

Slate is a metamorphic rock. Slate is actually shale that had low heat and not very much pressure put on it. Slate is mostly formed in mountain areas. It takes thousands of years for slate to change. Slate can be any color but is mostly found in gray or black. When it is broken, it splits into layers. It can have quartz, muscovite, hematite, graphite, and other minerals in it.

The slate or slate changes into schist
Slate is still a popular roofing material. Slate is often used to build a fireplace, especially in a rustic setting theme that some house-owners favour. Slate pieces are used to create decorated plaques, house numbers or names, etc, in many souvenir shops.
In North Wales, homes are often built using slate, a durable and weather-resistant rock that is abundant in the region. Slate is prized for its aesthetic appeal and natural properties, making it ideal for roofing and flooring. The local slate quarries have historically provided this material, contributing to the distinctive architectural style of the area. Additionally, the use of slate reflects the region's geological characteristics and cultural heritage.
Slate siding is made from the metamorphic rock slate.
