Answer: The correct option is D: Is alloyed with carbon and chromium to make stainless steel.
Explanation: Because of its physical characteristics, iron is a material that tends to oxidize easily. With the chromium alloy stainless steel is created, which for its quality can be used in the manufacture of structural steels.
Answer:
Mechanical weathering
Explanation:
Weathering is defined as the process by which rock materials are broken down by the action of physical or chemical processes. Physical weathering is known as mechanical weathering, where rocks breakdown into smaller pieces by mechanical means.
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away
Answer:
Front
Explanation:
When two air masses collide, a front is formed. The two most common types of fronts are cold fronts and warm fronts.
Cold fronts are formed by the advance of cold continental polar or continental arctic air towards the south. The colder air wedges underneath the warmer air mass to the south and causes it to rise, forming a storm front.
A warm front is the pushing action done by an advancing mass of maritime tropical warm and moist air that pushes a colder air mass out of the way by rising on top of it gradually and moving it away slowly. This causes an extensive cloud front of light rains.
