Answer:

The correct answer would be - 1. group 2.period 3. less 4. more

Explanation:

elements that have a place with same group contains same number of valence electrons. Thus, they will in general show comparable chemiccal properties.  

At the point when we move over a period at that point number of electrons get added to a similar shell. Therefore, there will be no expansion in size of elements.  

Additionally, metals are the elements that have a place with group 1, 2 and d-block group are otherwise called metals. Metallic character of elements diminishes when we move left to directly in a periodic table.  

As most responsive metals are put on the left half of occasional table.  

Since, size of elements increases on descending the groups. Along these lines, a elements can lose its valence electrons due to the less forrce of ttaraction between valence electrons and its neucleus.

Explain the role convection plays in the rock cycle
Romashka-Z-Leto [24]

Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. All rocks are made up of minerals. A mineral is defined as a naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure. A rock is any naturally formed, nonliving, firm, and coherent aggregate mass of solid matter that constitutes part of a planet.

What is the greatest current threat to the loss of Earths biodiversity
luda_lava [24]
The greatest current threat to the loss of the Earth's biodiversity is global warming. This is because when the ice melts, the cold comes down to us and makes us have rainy summers and very early snow and cold springs and cold autumns. And when the ice melts enough, water will start to come down and flood countries and cities, such as Manhattan. Scientists are predicting that California will break away from America.
