What effects would a higher gravity have on my world's geography and climate?

I'm currently designing a super earth with a surface gravity of 1.5g and a thick oxygen rich atmosphere. Now since the gravity is higher, how exactly would that affect my world? For example:

Geography

• Could there be mountains as tall as everest there?
• Since the atmosphere is thicker, would that cause a faster erosion?
• Would rivers, lakes or waterfalls be affected by the higher gravity?
• What about Volcanic and seismic activity? Do they get affected by higher gravity?
• What about the ocean topography? How does it get affected by the force of gravity?

Weather & Climate

• Since the atmosphere is thicker how would that affect the weather?
• What would the climate be like?
