WHO EVER ANSWERS FIRST IS GETTING BRAINLIEST ( Correctly ) Most geologists rejected Alfred Wegener’s idea of continental drift because

they were afraid of the new idea.

Wegener was too interested in what Earth was like millions of years ago.

Wegener used several different types of evidence to support his hypothesis.

Wegener could not identify what force could move the continents.

Wegener could not identify what force could move the continets.

Explanation:

Wegener could not identify what force could move the continents.

hope this helps

have a goood day :)

Explanation:

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
