The diagram shows a simple model of an event that is part of the rock cycle. image Which type of event is most likely occurring in the diagram? A. the compacting of layers by high pressure and heat that leads to metamorphic rock
B. the cementing of layers of sediment particles that leads to sedimentary rock
C. the melting of sediment particles that leads to igneous rock
D. the hardening of liquid magma that leads to igneous rock

In which of these cases are the two wave points considered to be in phase with each other?

An atom of sodium-23 (atomic number = 11) has a positive charge of +1. give this information, how many electrons does it have? how many proteins and neutrons does this atom have

Select the correct answer from each drop-down menu.describe what happens to a carbon-11 atom when it undergoes positron emission.the decay of a carbon-11 atom _1_, and this causes it to emit _2_.options for 1: > changes a neutron into a proton> changes a proton into a neutron> is hit with a neutron> reconfigures its protons and neutronsoptions for 2: > a negatively charged electron-sized particle> a positively charged election-sized particle> two atoms and several neutrons> two neutrons and two protons
