Answer:
oxidation
Explanation:
oxidation is a chemical weathering process whereby the iron compounds in the rock react with the oxygen in the air to produce a reddish brown coating.
it occurs only on rocks that contain iron for example sandstone. the dissolved oxygen in both the soil and air react with the iron minerals in rocks to oxidize and become iron oxide and the iron becomes rust forming the red color. iron oxide either remains in the soil or rocks as reddish brown coating or in waterlogged areas it can be removed in solution.
the chemical process for oxidation is FeO=Fe2O3

Answer:
Radiometric dating provides the age (absolute) of the rocks
Explanation:
The law of superposition says that the rocks that are found at the base of the undisturbed sedimentary rock sequence are the oldest rocks and the rocks that are found at the apical region are the youngest rocks. This gives the relative age of the rocks but the absolute age cannot be determined.
On the other hand, Radiometric dating refers to the technique of dating the rocks and obtaining the age of the rocks by determining the rate at which the unstable radioactive elements decay. This gives the absolute age of the rocks and is very commonly used by geologists.
Thus, the radiometric dating method tells the absolute age of the rocks but the law of superposition of rocks cannot.
Answer: B. Confining pressure decreases on a rising magma, allowing gas bubbles to expand and fracture the magma. This process further decreases pressure on the magma and will result in an explosive event.
Explanation: The bubbles inside the magma are responsible for making it bubble to the surface of the earth crust and the explosion that follows. As magma rises to the surface of the earth, it absorbs gases and water vapor which forms bubbles in the magma. As the pressure decreases in the magma, it causes these bubbles to increase. When the rise of magma cannot keep up with he growth in the bubbles, there is an explosive eruption to the surface. Compare this to shaking a Coca Cola bottle before opening it.
If the magma rise keeps us with the gas bubbles, the eruption is not explosive.
Answer:
Boreal forest
Explanation:
The boreal forest is a biome that is found in the Northern Hemisphere. It is located between the temperate forests and the tundra. These forests are dominated by coniferous trees. The climate is continental, with the winters being very cold and snowy, while the summers are pleasant with mild temperatures. The animals that live in these forests are the elk, moose, deer, wolverines, wolves, black bears, mink, foxes, lynx, among others. All these animals have special adaptations that enable them to live in this biome. They all have thick fur for most of the year, only shedding slightly during the summer.Their paws tend to winder and have goo isolation so that they can walk easily on the snow and avoid frostbite. It is not a biome that has very big diversity in flora and fauna, but it is not a one that lacks in it as well.
