What is a terminal moraine made of?
Regional SpecificsA terminal, or end, moraine consists of a ridgelike accumulation of glacial debris pushed forward by the leading glacial snout and dumped at the outermost edge of any given ice advance. It curves convexly down the valley and may extend up the sides as lateral moraines. How are terminal moraine created? Terminal moraines form when

What skills do you need to become a mineralogist?
Regional SpecificsBecoming a mineralogist requires at least a bachelor’s degree, usually in mineralogy, geology, or sometimes engineering. These programs focus on geology, chemistry, other sciences, and math. Some mineralogist jobs are posted as engineering positions. Is a mineralogist a geologist? Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure,

Why do plants grow well in volcanic soil?
Regional SpecificsThese minerals include sulfur, potassium, and phosphates, which plants often have a hard time getting. When combined with heavy rainfall, volcanic soil becomes very fertile, or good for growing plants. Is volcanic soil good for plants? By adding volcanic rock dust back to the soil, it makes it accessible to plant roots as soon as

Why is the moon no longer geologically active?
Regional SpecificsThe moon is no longer geologically active because: it is small so has lost most of its internal heat. Is the Moon still geologically active? In 2012, new observations showed surface features, called graben, which form where the crust has pulled apart; these features are evidence that the Moon is expanding in some places. These

What is form of a mineral?
Regional SpecificsThe four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which … What are 3 ways minerals

How do we know earth’s outer core is liquid?
Regional SpecificsBy tracking seismic waves, scientists have learned what makes up the planet’s interior. P-waves slow down at the mantle core boundary, so we know the outer core is less rigid than the mantle. S-waves disappear at the mantle core boundary, so the outer core is liquid. How do we know that Earth’s core is liquid?
