What is a similarity between weathering and erosion

You can't have erosion without weathering weakening a rock first.

Explanation:

Weathering is the process where rock is dissolved, worn away or broken down into smaller and smaller pieces. There are different ways this can be done, either mechanically, chemically or organically.

Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
