Adult Cloverfield monster vs MCU Surtur

I’ve doubted that the Cloverfield monster as an adult is 2km huge so what happens here?

Going with Surtur because Cloverfield monster ( also like Surtur ) do not have enough feats, Surtur looks bigger ( 4 km i remember ) and Surtur simply stabs with sword

Isn´t the Cloverfield monster at least 100km large?? In the final scene he came over the earth atmosphäre which should be at least 100km.

Surtur throws a mountain on the creature or uses his enormous strength to throw it into space, he can cut it in half because he is bigger than the monster at his full size and his sword probably weighs hundreds of times more than the adult monster. He could probably disintegrate it with AoE attacks that were melting Entire buildings and was able to destroy Odin's vault also. He wins 9/10.

@tyki_mikk25: It was above clouds it was nowhere near the atmosphere it is probably 3 kilometers at best.

@tyki_mikk25: Cloud level can be as low as 360 meters.

It also has no feats. Surtur steps on it.
