Depends what you're asking...If the earth was smaller but not you, you would weigh the same. It's just like if the USA or Britain smaller than now or shrunk, we would be the same.
The sun would look much smaller than it does from Earth but still bright.
If the planet is smaller, then it can't have the same size. If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller. If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface gravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general.
Yes, a higher albedo would result in an overall cooler climate. A higher albedo means that more sunlight is reflected back into space instead of being absorbed by the Earth's surface, which would lead to lower temperatures.
No, if Earth's albedo was higher and it was farther from the sun, it would receive less solar radiation, leading to cooler temperatures overall. Albedo affects how much incoming solar radiation is reflected back into space, but distance from the sun determines how much solar radiation reaches Earth in the first place.
A smaller Earth would cool faster because there would be less heat-generating radioactive elements in its core. This would result in a cooler interior temperature, not a warmer one.
If the Sun's temperature were much colder and it were much smaller Earth would no longer support human life
If Earth's interior had the same composition as the crust, the planet would be cooler and less dynamic. This would result in reduced geological activity such as volcanoes, earthquakes, and plate tectonics. The lack of differentiation in the layers would also impact the magnetic field and the generation of Earth's protective atmosphere.
The earth would be quite a bit cooler and darker than it is now.
the earth would die
In reality, the interior of the Earth is slowly cooling. In human time perspective, however, this cooling has no impact.
I sure would!

What forces would lead to the movement of the plates over the surface of the earth? At this time it is believed this movement results from mantle convection. Deep within the earth there is a large amount of heat coming from two sources: the magma remnants of the Great Bombardment, and radiation from radioactive elements. This heat, in accordance with the 2 ndlaw of thermodynamics, must flow to a cooler place, and subsequently rises to the surface of the Earth. If the Earth were smaller, this heat would flow by conduction, but because of the relatively large size of the Earth, convection also takes place. Thus, as in heating a pot of water on a stove, convection currents are established within the earth, which bring warm material to the surface and send cooler material to the interior.
If the mantle of the earth interior were to cool down the convection currents and plate tectonics would stop. That would mean that there would be no more earthquakes or volcanoes.
