Answer:
What are the uses of Bases
Uses of Bases
1. Calcium Hydroxide (Slaked lime) [Ca(OH)2]
It is used to neutralize the acidity in soils.
It is an ingredient in whitewash and mortar.
It is a component of the Bordeaux mixture used for protecting agricultural crops from pests.
It is used in the preparation of dry mixes for painting and decorating.
2. Magnesium Hydroxide (Milk of magnesia) [Mg(OH)2]
It is used as an antacid or a laxative. It helps to correct excess acidity in the stomach.

Erosion means taking away the soil. if soil moved away then it causes wears down of earth surface.
Answer:
Continental - Oceanic convergence
Continental - Continental convergence
Oceanic - Oceanic convergence
Explanation:
The convergent plate boundaries are the plate boundaries where the tectonic plates collide. As they collide, one of the plates slowly subducts below the other plate, creating a subduction zone. This type of plate boundary can be separated into three subtypes:
- Continental-Oceanic convergence; this subtype is a convergent plate boundary between an oceanic and continental plate. The oceanic plate subducts below the continental plate because it is lower and denser. As it does, near the subduction zone lot of volcanic activity occurs, often resulting in volcanic island chains.
- Continental-Continental convergence; this subtype is a convergent plate boundary between two continental plates. As they collide, the smaller plate moves very slowly below the large plate, lifting up the surrounding area and creating large mountain chains.
- Oceanic-Oceanic convergence; this subtypeis a convergent plate boundary between two oceanic plates. One of the oceanic plates moves below the other, creating subduction zone. This subduction zone also creates a lot of volcanic activity, resulting in underwater volcanoes, or volcanic islands.
