9. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
10.Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage.
11.The feldspar-group, a very complex mixture of oxygen, silicon, aluminum and trace elements like sodium, potassium, calcium and more exotic elements like barium, are by far the most common minerals, making up almost 58% of all to a geologist accessible rocks, especially magmatic and metamorphic ones.
12.minerals are really very important in our life as they are used in our daily purposes and we use for example iron daily we use iron almirahs etc ,......
we use aluminium, diamond etc . in our daily life we use aluminium foils that are used to pack food items etc ,. there are many examples such as these ....
Minerals are play important role in our life. Everything we use from a tiny ship to tower are building is made from a mineral. We use minerals in our daily life for example tooth paste its cover and brush everything is made from minerals. All living things also need minerals
No a rock is not that strong
Answer:
#1 - Habitat destruction renders entire habitats functionally unable to support the species present; biodiversity is reduced in this process when existing organisms in the habitat are displaced or destroyed. The primary cause of species extinction worldwide is habitat destruction
#2 - All forms of pollution pose a serious threat to biodiversity, but in particular nutrient loading, primarily of nitrogen and phosphorus, which is a major and increasing cause of biodiversity loss and ecosystem dysfunction. In addition, nitrogen compounds can lead to eutrophication of ecosystems.
#3 - Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats.
#4 - Overexploitation means harvesting species from the wild at rates faster than natural populations can recover. Two birds that were victims of overhunting are passenger pigeons and great auks (a type of bird). Both were hunted to extinction.
#5 - The core threats to biodiversity are human population growth and unsustainable resource use. To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting. ... Habitat loss occurs through deforestation, damming of rivers, and other activities.
