Why some parts of the Earth's surface are mineral-rich while others are mineral-poor?
certain geological conditions are needed for their formation in deposits large enough to
be worth mining
areas of old hard igneous rocks / old shield area (e.g. Canada, Baltic, Southern Africa) is
one example
another is in young fold mountain ranges with recent and great earth movements
fossil fuels relate to presence of tropical forests / shallow swamps 150-300 million years

How does water affet the formation of the earths surface?
Water does everything. As a body of water, it erodes cliffs, roacks, and beaches. As rain, it makes some areas fertile and leaves others barren.
What is the study of earths surface and how people use it?
Others study the impact of human activity on Earth's environment, and design methods to protect the planet. Some use their knowledge about Earth processes such as volcanoes, earthquakes, and hurricanes to plan communities that will not expose people to these dangerous events.
What is the name of opening in the earths crust where hot melted rocks from inside the earth come to the surface?
The opening in the Earth's crust where hot melted rocks from inside the Earth come to the surface is known as a volcano. When pressure builds up beneath the Earth's surface, it can lead to volcanic eruptions, where magma, ash, and gases are expelled. Volcanoes can vary in size and activity levels, with some being constantly active while others remain dormant for long periods.
What are cracks in the earth's surface?
"Fissure" is one word meaning a crack in the surface of the Earth. Others are "fault" and "rift".
How big is earth in realation to other planets?
In terms of Radius and diameter; Mercury's radius and diameter (at the equator) = 0.3825 x that of Earths (or 38.25%) Venus's radius and diameter = 0.9488 x Earths (nearly 95%) (Earth's radius = 6378km, diameter = 12756km) Mars = 0.5323 x Earths (53.2%) Jupiter = 11.21 x Earths Saturn = 9.45 x Earths Uranus = 4.01 x Earths Neptune = 3.88 x Earths In terms of Volume; Mercury's volume = 0.056 x Earths (or 5.6% of Earths) Venus' volume = 0.857 x Earths (85.7%) (Earths volume = 1.08 x 1012 cubic km (km3)) Mars' volume = 0.151 x Earths (15.1%) Jupiter's volume = 1321.3 x Earths Saturn's volume = 763.59 x Earths Uranus' volume = 63.086 x Earths Neptune's volume = 57.74 x Earths
Why are some density currents warm and others cold?
there are some warm currents as they flow along the earths surface while there some cold currents as they travel below the earths surface

Was the discovery of Francium delayed because of a lack of technology at the time among other reasons?
Francium was found 80 years after the others because it is very rare on the Earths surface and there is less than an ounce of it in the earths crust. Also the fact that the technology was limited didn't help.
Which process produces rising air due to unequal heating of earths surface?
Frontal wedging
How do earthquakes change earth's surface?
Earthquakes change earth by moving earths plates
What is the blanket of protective gases that covers the earths surface?
The blanket of protective gases that covers the Earth's surface is the atmosphere. It is composed of various gases such as nitrogen, oxygen, carbon dioxide, and others, which help regulate the planet's temperature and protect it from harmful solar radiation.
Continents are moving across the Earths Surface under continental drift One continent is moving significantly more slowly than the others Which one is it?
The continent that is moving significantly more slowly than the others is Antarctica. It has been described as the slowest moving continent due to its unique position and the way it is situated on the Earth's surface.
What is a layer of gasses above earths surface?
The layer of gases above Earth's surface is called the atmosphere. It is composed of various gases such as nitrogen, oxygen, carbon dioxide, and others. The atmosphere plays a crucial role in regulating the planet's temperature and protecting life on Earth from harmful solar radiation.
Can a volcanic mountain form underwater and on earths surface?
Some volcanoes arise on land; others begin under the seabed and eventually grow tall enough that part of them is above water. Volcanic islands such as Hawaii are an example of this second type.
How much of the earths deserts are covered by sand dunes?
About 20% of the deserts are covered by sand. Others are covered by soil or rock.
What is the study of earths surface and how people use it?

What kind of Bacteria does Scientists think was or is on Mars?
